• Skin-like Devices for Wireless Monitoring of Vital Signs in Neonatal Intensive Care
    Battery-free, 'epidermal' electronics with advanced capabilities in data transfer, in-sensor analytics and bi-nodal function enable wireless, clincal-grade measurement of full vital signs information from fragile neonates. By comparison to conventional, hard-wired monitoring systems, these technologies greatly reduce risks for injuries to the delicate neonatal skin, they eliminate constraints on natural movements of the baby, and they facilitate skin-skin contact and bonding between parent and child.
  • Microscale, Remote-controlled Terrestrial Robots
    Sub-millimeter scale robots are of interest for applications in areas such as minimally invasive surgeries. Unique approaches in manufacturing and actuation enable untethered, terrestrial robots with complex, three-dimensional geometries and heterogeneous materials construction. Modes of locomotion and manipulation span from bending, twisting, and expansion, to linear/curvilinear crawling, walking, turning, and jumping via laser-induced local thermal actuation. Photonic structures such as retroreflectors and colorimetric sensing materials support simple forms of wireless monitoring and localization.
  • Multifunctional 3D Mesostructures as Neural Interfaces to Cortical Spheroids (Mini-Brains) and Engineered Assembloids
    Three-dimensional (3D), sub-millimeter-scale constructs of neural cells, known as neural spheroids and organoids, are of rapidly growing importance in neuroscience research due to their ability to reproduce complex features of brain architecture, function and organization in vitro. We have developed complaint, shape-matched mesoscale platforms in precisely engineered 3D geometries that gently envelop the spheroids/organoids to establish multifunctional electronic, optoelectronic, thermal, mechanical and biochemical interfaces to these systems for fundamental studies of their behaviors. Demonstrations include their application to human induced pluripotent stem cell-derived cortical spheroids and assembloids.
  • Skin-Integrated Flexible Electronic Systems as Haptic Interfaces for Virtual Reality
    By comparison to the eyes and the ears, the skin is a relatively underexplored interface for VR/AR technology that could, nevertheless, greatly augment a virtual experience. We have developed a wireless, battery-free platform of electronic systems and haptic interfaces that softly laminate onto the skin to communicate information via spatio-temporally programmable modes of mechanical vibration. The resulting epidermal VR systems create many new opportunities where the skin provides a communication and sensory input to the body, as demonstrated in social media/personal engagement, gaming/entertainment and prosthetic control/feedback.
  • Soft Implantable Optoelectronics for Real-Time, Closed-Loop Control of Organ Function
    Bio-optoelectronic systems enable closed-loop peripheral neuromodulation to alleviate organ dysfunction. In the context of overactive bladder in a rat model, this fully implantable wireless platform monitors and modulates bladder function in real-time, a closed-loop fashion through optogenetic modulation of bladder-projecting sensory afferents. The results form the foundations of an advanced engineering approach to intervention for bladder dysfunction, and a generalizable idea for bio-optoelectronic schemes to treat other disease types.
  • Bioresorbable Electronic Medicines for Accelerated Neuroregeneration
    Bioresorbable electronic implants allow for wireless delivery of electrical stimulation directly to the site of a damaged nerve. Proper 'dosing' of such stimulation throughout the course of a healing process yields significant improvements in the regenerative rate and final functional outcomes. After this operational period, the device naturally resorbs and disappears without a trace, without the need for surgical extraction - the result is the first example of a bioresorbable 'electronic medicine', or 'electroceutical', with capabilities that could complement those of traditional pharmaceutical approaches.
  • Skin-Like Microfluidic Systems for Capture, Storage and Chemical Analysis of Sweat
    Soft, flexible and stretchable microfluidic systems, including embodiments that integrate wireless communication electronics, can intimately and robustly bond to the surface of skin without chemical or mechanical irritation. This integration defines an access point for a small set of sweat glands such that perspiration spontaneously initiates routing of sweat through a microfluidic network and set of reservoirs. Embedded chemical reagents respond in colorimetric fashion to markers such as chloride and hydronium ions, glucose and lactate. Wireless interfaces to digital image capture hardware on a smartphone serve as a means for quantitation.
  • Thin, Battery-free, Skin-like Devices for Blood Oximetry
    Wireless power transfer and data communication strategies provide the foundations for 'epidermal' light emitting devices that are capable of clinical-quality measurements of optical properties of the skin, with ability to capture photoplesmyograms for determination blood oximetry, heart rate, heart rate variability and other characteristics related to cardiovascular health. The initmate skin interface enables levels of measurement fidelity and user comfort that cannot be achieved with traditional, wrist-mounted wearables.
  • Microscale Kirigami via Mechanical Buckling -- Electronic Pop-up Books
    Colorized scanning electron micrographs of 3D structures formed by a mechanically directed self-assembly process, in which thin materials patterned in 2D by semiconductor manufacturing techniques spontaneously rise up out of the plane to yield 3D architectures with engineering control. The resulting capabilities far exceed anything that is possible with traditional 3D printing techniques..
  • 3D Microarchitectures in Device-Grade Silicon
    Colorized scanning electron micrograph of a complex, three-dimensional structure formed by transformation of a planar, two-dimensional precursor. Controlled buckling follows from compressive forces that act at precise locations across the structure upon release of prestrain in an elastomeric substrate. This example uses microscale ribbons and plates of silicon, with potential applications in electronic circuits, battery anodes, photodetectors, and other semiconductor devices.
  • A Digital Camera With a Design Inspired by the Insect Eye
    In arthropods, evolution has created a remarkably sophisticated class of imaging system, with wide angle field of view, low aberrations, high acuity to motion and infinite depth of field. We demonstrated materials and fabrication schemes for arthropod-inspired cameras with numbers of imaging elements comparable to those found in the eyes fire ants and bark beetles The devices combine elastomeric compound optics with deformable arrays of thin silicon photodetectors, in co-integrated sheets that can be blown up like a balloon.
  • Soft, Microfluidic Assemblies of Circuits, Sensors and Radios for the Skin
    Chip-scale components contained in thin, elastomeric microfluidic structures and interconnected with 'origami' type wiring networks yield stretchable wireless systems that can gently but robustly integrate with the surface of the skin for multifunctional physiological status monitoring. The ability to use off-the-shelf integrated circuits, sensors and radios in skin-compatible, soft designs opens up many near-term opportunities in healthcare and non-healthcare related applications alike.

  • A Physically Transient Form of Electronics
    Silk, magnesium, magnesium oxide, silicon dioxide and silicon nanomembranes provide a collection of materials for high performance integrated circuits, actuators, sensors and power supply systems that dissolve, completely and with controlled rates, in water or biofluids. Potential applications of this transient electronics technology range from resorbable medical implants, to degradable environmental monitors, to compostable consumer devices. The image illustrates a transient electronic circuit in a state of partial dissolution in a puddle of water
  • 3D Electronic Pericardium
    Ultrathin, 3D elastic membranes shaped precisely to match the epicardium serve as platforms for deformable arrays of multifunctional sensors, electronic and optoelectronic components. Such integumentary devices completely envelop the heart, in a form-fitting manner, to provide a mechanically stable biotic-/abiotic interface during normal cardiac cycles. These systems form an 'artificial pericardium' with advanced functional capabilities in sensing and stimulation, of relevance for both basic studies and clinical use.
  • Epidermal Photonics
    Systems that combine pixelated arrays of thermochromic liquid crystals and wireless electronics on thin, soft elastomers yield physical properties - modulus, elastic strain limit, thickness and thermal mass - that are matched to the epidermis, for precise thermal characterization of the skin. The results can be used to determine cardiovascular health, progressions in wound healing cascades and other parameters of relevance to human health.
  • Flexible, Adaptive Camouflage System With a Design Based on the Cephalopod Skin
    This multilayered, multifunctional system adopts a bio-inspired design, derived from study of the skins of cephalopods, i.e. squid, octopus, cuttlefish. Here, a color-changing collection of pixels (analogous to the chromatophores and leucophores in a cephalopod) in the top layer automatically configures itself to match any pattern of illumination from the surrounding environment. A distributed array of ultrathin silicon photodetectors (analogous to opsins) provides information that controls a corresponding set of actuators (analogous to muscle fibers).
  • Phase Separated Nanostructures in Printed Lines of Block Copolymers
    Superfine resolution jet printing techniques and processes of self-assembly in block copolymers can be exploited together to form well-defined nanostructures in wide-ranging, hierarchical geometries with length scales from centimeters to nanometers. Multiple polymers with different molecular weights or mixtures of molecular weights can be printed onto a single substrate, to provide access to patterns with diverse layouts and feature sizes for applications in advanced nanolithography.
  • Greek Cross Fractal Design for a Stretchable Electrophysiological Sensor and Temperature Detector
    Thin films of hard electronic materials patterned into filamentary, fractal structures and embedded in soft elastomers provide routes to compliant, skin-like devices for physiological monitoring and interventional medicine.
  • Nanoscale Thermocapillary Flow As a Route to Arrays of Semiconducting Carbon Nanotubes
    Electrical current selectively injected into metallic nanotubes in aligned arrays leads to thermocapillary flows in amorphous organic thin film coatings. The trenches that result from this process leave these tubes exposed, to allow their selective removal. The semiconducting tubes that are left behind can be integrated into high performance electronics and digital integrated circuits.
  • Mechanical Energy Harvester on the Surface of the Heart
    Wearable electronics, biomedical implants, environmental monitors and many other types of devices could benefit from approaches to power supply that do not require batteries. Means for harvesting power directly from the ambient environment or from natural processes of the body represent attractive possibilities. This image shows a thin, flexible device that can harvest and store energy from the mechanical motions of the heart, lung and/or diaphragm, at levels that meet requirements for pacemakers and other existing implantable devices.
  • Stretchable Lithium Ion Battery
    Thin, elastomeric substrates, distributed arrays of active materials, and 'spring-within-a-spring' interconnect structures yield a kind of rechargeable lithium ion battery that has the mechanics of a rubber band. Such devices could be useful for powering electronic circuits that laminate onto the skin or other surfaces of the human body.
  • Spatio-temporal mapping of brain activity during epileptic seizures
    Flexible, bio-integrated sheets of sensors and electronics provide new tools for mapping electrical activity in the brain, with unprecedented spatial and temporal resolution. The resulting technology is providing new insights into the neuroscience of epilepsy, in a form that also has clinical relevance for surgical procedures used to treat the most acute cases of epilepsy. The image shown here is a color representation of electrical potential measured across the surface of the brain of a feline animal model, recorded during an induced seizure.
  • A Cellular-Scale, Injectable Optoelectronics Technology
    In neuroscience, an ability to insert light sources, detectors, sensors and other components into precise locations of the deep brain could yield versatile and important capabilities. We recently reported an ultrathin, 'injectable' class of cellular-scale optoelectronics that offers such features, with examples of completely wireless and programmed complex behavioral control over freely moving animals. The ability of these ultrathin, mechanically compliant, biocompatible devices also can be used in other organ systems. The image shows a representative device, threaded through the eye of a needle.
  • Large Area Negative Index Metamaterials
    High resolution printing techniques enable the formation of large-area sheets of materials that display negative index of refraction, for advanced imaging devices, photonic components and sensors.
  • Epidermal Electronics
    Specially designed materials, geometrical forms and integration layouts enable electronic systems with physical properties matched to the epidermis, suitable as a new class of skin-integrated device for applications in physiological status monitoring, wound measurement/treatment, human/machine interfaces, covert communications and others.
  • Stretchable Silicon Integrated Circuit
    These devices use silicon nanomaterials in ultrathin layouts that place the active materials in the neutral mechanical plane, i.e. the plane where bending induced strains are zero. Bonding this type of circuit to a prestretched rubber substrate leads to 'wavy' shapes that behave mechanically much like an accordion bellows when stretched or compressed. The result is a stretchable, high performance circuit technology.
  • slide Electronic eyeball camera
    This advanced camera uses a hemispherically curved array of photodetectors, in a design inspired by the human retina. This layout enables wide angle fields of view, with uniform illumination and very low aberrations, even when very simple imaging optics are used.
  • slide Bio-integrated electronics for cardiac therapy
    This flexible, waterproof circuit can wrap the surface of the heart, to produce high resolution 'maps' of electrical behavior of the cardiac muscle, during beating. The data can help surgeons locate aberrant tissues that are responsible for certain types of arrhythmias.
  • slide Flexible Silicon Microcell Photovoltaics
    This unusual PV device consists of an interconnected collection of microbars of silicon, created by controlled etching and release from a silicon wafer followed by transfer printing onto a thin sheet of plastic. The device offers the performance of conventional, rigid silicon modules, but with the lightweight, mechanically flexible construction found in organic photovoltaics.
  • slide Electronics on Balloons: Instrumented Surgical Catheters
    This advanced cardiac surgical and diagnostic device involves high performance semiconductor components (e.g. microscale LEDs), RF ablation electrodes and multi-modal sensors, all integrated into the inflatable surface of an otherwise convetnional balloon catheter. Advanced materials, device designs and concepts in mechanics enable these systems to function at levels of inflation that corresponds of strains of nearly 200%.

We seek to understand and exploit interesting characteristics of 'soft' materials, such as polymers, liquid crystals, and biological tissues, and hybrid combinations of them with unusual classes of inorganic micro/nanomaterials -- ribbons, wires, membranes, tubes or related. Our aim is to control and induce novel electronic and photonic responses in these materials, and to develop new 'soft lithographic' and biomimetic approaches for patterning them and guiding their growth. This work combines fundamental studies with forward-looking engineering efforts in a way that promotes positive feedback between the two. Our current research focuses on soft materials for conformal electronics, nanophotonic structures, microfluidic devices, and microelectromechanical systems, all lately with an emphasis on bio-inspired and bio-integrated technologies. These efforts are highly multidisciplinary, and combine expertise from nearly every traditional field of technical study.
