Prof. Zhenan Bao et al discuss the operational principles, device design, material selection, and fabrication considerations for stretchable transistors in future wearable and implantable integrated circuits.

Prof. Zhenan Bao et al have developed a hybrid wearable system of soft sensors and flexible printed circuit board, which wirelessly communicates with a smartphone app, and demonstrate that the system can perform cortisol sensing from human sweat under acute stress events.

Prof. Renee Zhao et al present a magnetically actuated milli-spinner robot that navigates complex and high-flow vasculature and enables multifunctional treatment, including localized suction and shear for efficient clot removal, targeted drug delivery, and in situ embolization for aneurysm treatment.

Professors Zhenan Bao, James Dunn, Julia Kaltschmidt, Xiaoke Chen, Xiang Qian et al report NeuroString, a small, soft fiber made of skin-like material that can host thousands of electronic channels, which could be implanted in the body to sense chemicals, deliver drugs, stimulate muscles or nerves, and monitor bodily activity, or outside the body, could enable new smart fabrics, wearable devices, and soft robotics.

Prof. Eric Pop et al assessed the performance of single-junction multilayer TMD solar cells under various indoor lighting conditions and found that their power conversion efficiency could outperform commercial indoor photovoltaic technologies for powering IoT devices.

Prof. Gordon Wetzstein et al present an ultra-thin MR display design that combines waveguide holography and artificial intelligence (AI)-driven holography algorithms to create visually comfortable and perceptually realistic 3D MR experiences in a compact wearable device.

Prof. Zhenan Bao, Prof. Carla Pugh et al designed a proof-of-concept multilayer, soft electronics capable of sensing damage in three dimensions, which may lead to practical applications damage-intelligent soft robots and in surgical simulation technology.

Prof. Daniel Palanker, Dr. Mohajeet Bhuchory et al find that a 3D honeycomb-based approach to high resolution subretinal prosthesis has more promise than a prior design that used flat bipolar pixels.

Prof. Mark Brongersma, Prof. Nicholas Melosh, Prof. Eric Appel et al demonstrate dynamic, high-resolution color tuning and high-diffraction-efficiency beam-steering devices that operate at CMOS-compatible voltages, highlighting that the deformability of soft materials can enable body-worn technologies.

Prof. Nicholas Melosh, Siddarth Doshi et al describe a method for heat-treating PEDOT:PSS films that make them water-stable without the need for cross-linking materials, for use as mixed ionic-electronic conductors in bioelectronics.
