As rubber-like elastomers have led to scientific breakthroughs in soft, stretchable characteristics-based wearable, implantable electronic devices or relevant research fields, developments of degradable with comparable mechanical properties could bring similar technological innovations transient, bioresorbable electronics expansion into unexplored areas. Here, we introduce ultra-stretchable, biodegradable capable stretching up ~1600% outstanding toughness, tear-tolerance, and storage...
Recent advances in passive radiative cooling systems describe a variety of strategies to enhance efficiency, while the integration such technology with bioinspired design using biodegradable materials can offer research opportunity generate energy sustainable manner, favorable for temperature/climate system planet. Here, we introduce stretchable and ecoresorbable cooling/heating engineered zebra stripe-like patterns that enable generation large in-plane temperature gradient thermoelectric...
Current standard clinical options for patients with detrusor underactivity (DUA) or underactive bladder─the inability to release urine naturally─include the use of medications, voiding techniques, and intermittent catheterization, which patient inserts a tube directly into urethra eliminate urine. Although those are life-saving there still unfavorable side effects, including urinary tract infection (UTI), urethritis, irritation, discomfort. Here, we report wireless, fully implantable,...
Substrates or encapsulants in soft and stretchable formats are key components for transient, bioresorbable electronic systems; however, elastomeric polymers with desired mechanical biochemical properties very limited compared to non-transient counterparts. Here, we introduce a elastomer, poly(glycolide-co-ε-caprolactone) (PGCL), that contains excellent material including high elongation-at-break (< 1300%), resilience toughness, tunable dissolution behaviors. Exploitation of PGCLs as polymer...
Although biodegradable, transient electronic devices must dissolve or decompose via environmental factors, an effective waterproofing encapsulation system is essential for reliable, durable operation a desired period of time. Existing protection approaches use multiple alternate layers electrically inactive organic/inorganic elements combined with polymers; however, their high mechanical stiffness not suitable soft, time-dynamic biological tissues/skins/organs. Here, we introduce...
Current research in the area of surgical mesh implants is somewhat limited to traditional designs and synthesis various materials, whereas meshes with multiple functions may be an effective approach address long-standing challenges including postoperative complications. Herein, a bioresorbable electronic presented that offers high mechanical strength over extended timeframes, wireless post-operative pressure monitoring, on-demand drug delivery for restoration tissue structure function. The...
Abstract Effective encapsulation is essential for reliable operation of bio‐integrated electronics, particularly those containing dissolvable elements, under humid environments desired periods time; however, conventional inorganic or organic encapsulants often suffer from tissue‐incompatible mechanical rigidity and insufficient water‐barrier performance. Here, a mechanically resilient efficient strategy proposed that can exceed functional lifetime state‐of‐the‐art soft encapsulations by...
Abstract Soft robots have partially or entirely provided versatile opportunities for issues roles that cannot be addressed by conventional machine robots, although most studies are limited to designs, controls, physical/mechanical motions. Here, we present a transformable, reconfigurable robotic platform created the integration of magnetically responsive soft composite matrices with deformable multifunctional electronics. Magnetic compounds engineered undergo phase transition at low...

Optogenetics is a new neuroscience technology that uses light-responsive proteins to stimulate neurons with light and control the emotions and/or behavior of animals. There are few approaches deliver in vivo, including using an optical fiber can send from external source target neuron, directly inserting light-emitting device, shooting penetrate tissue outside. Among these methods, wireless device capable being used for experiment while leaving animal completely free method has been studied...
Abstract As the demand for power systems, including portable ones, is growing at an ever‐faster pace, many studies are approaching to discover innovative materials current battery technology or replace existing ones with new systems through mimicking living things nature. Here, a soft, solid‐state storage system featuring electric eel‐inspired artificial organs capable of converting chemical potential ionic gradient into electricity introduced. These constructed assembly low and high...
