Portable thermoacoustic imaging for biometric authentication

Prof. Amin Arbabian et al present the first known instance of a silicon IC being used as the output stage of the transmitter for a thermoacoustic imaging system.

Sensing leg movement enhances wearable monitoring of energy expenditure

Prof. Steven Collins, Prof. Scott Delp, Prof. Mykel Kochenderfer and Patrick Slade present a wearable system that estimates metabolic energy expenditure in real-time during common steady-state and time-varying activities with substantially lower error than state-of-the-art methods.

High-performance flexible nanoscale transistors based on transition metal dichalcogenides

Prof. Eric Pop et al describe flexible nanoscale field effect transistors based on 2D semiconductors, such as MoS2, MoSe2 and WSe2, their fabrication, and properties.

Optimizing depth perception in virtual and augmented reality through gaze-contingent stereo rendering

Prof. Gordon Wetzstein et al introduce a stereo rendering technique that models the gaze-dependent shift of the no-parallax point in the human eye and show that gaze-contingent stereo rendering improves the perceptual realism and depth perception of emerging wearable computing systems.

Conjugated polymer for implantable electronics toward clinical application

Prof. Zhenan Bao et al review polymeric devices that have shown feasibility in studies with potential for clinical adoption.

Wearable vibrotactile stimulation (VTS) for upper extremity rehabilitation in chronic stroke: clinical feasibility trial using the VTS glove

Caitlyn Seim, Steven Wolf and Thad Starner show that VTS applied to a disabled limb may positively impact tactile perception, tone and spasticity, and voluntary range of motion.

Design considerations of a wearable electronic-skin for mental health and wellness: balancing biosignals and human factors

Prof. Pablo Paredes, Prof. Zhenan Bao, Prof. Boris Murmann et al. outline design considerations of a wearable device for continuously measuring physiological parameters linked to chronic stress and resulting mental health conditions.

Gait features for discriminating between mobility-limiting musculoskeletal disorders

Prof. Matthew Smuck et al determine different sensor-based gait parameters for distinguishing between patients with lumbar spinal stenosis versus knee osteoarthritis.

How is flexible electronics advancing neuroscience research?

Prof. Guosong Hong, Prof. Alberto Salleo, et al discuss that flexible electronics will play a major role in neuroscience studies and neurological therapies via neuromorphic devices on flexible substrates and the development of enhanced methods of neuronal interpenetration.

Validation and comparison of instrumented mouthguards for measuring head kinematics and assessing brain deformation in football impacts

Prof. David Camarillo, Prof. Gerald Grant, Prof. Michael Zeineh et al test three kinds of mouthguards and discuss their accuracy and implications for design.
