Diabetic foot ulcers are chronic wounds that affect millions and increase the risk of amputation mortality, highlighting critical need for their early detection. Recent demonstrations wearable sensors enable real-time wound assessment, but they rely on bulky electronics, making them difficult to interface with wounds. Herein, a miniaturized, wireless, battery-free monitor measures lactate in seamlessly integrates bandages conformal attachment bed is introduced. Lactate selected due its...
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...
Abstract Biocompatible and biodegradable polymer composite systems equipped with electrical/mechanical functions have been researched as a tool that can be applicable for bio‐integrated electronics to obtain variety of useful information, through formation reliable interfaces soft, non‐planar skin organs in the human body. Although previous review articles explored various types organic materials (natural/synthetic polymers), including intrinsically conducting polymers (ICPs) constituent...
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...
