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...
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...
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...
As the regenerative mechanisms of biological organisms, self-healing provides useful functions for soft electronics or associated systems. However, there have been few examples where all components properties while also ensuring compatibility between to achieve multifunctional and resilient bio-integrated electronics. Here, we introduce a stretchable, biodegradable, conductor constructed by combination two layers: (i) synthetic elastomer (ii) conductive composite with additives. Abundant...
