Preventive approaches, such as glutenin-genipin cross-linked coatings, effectively reduce plastic shedding under harsh conditions using biodegradable materials; however, they address only source control and lack proven scalability.

Built from biodegradable materials that undergo hydrolysis or enzymatic degradation, these systems are particularly well suited for temporary implantable applications, such as neural monitors, wireless

• lifetime control through strategies such as protective encapsulation. This Perspective outlines critical opportunities and technical directions to guide the development of next-generation transient electronic systems. Keywords: biodegradable/bioresorbable electronics; biodegradable materials

• protective PI layer is extremely thin, it can be selectively removed by reactive ion etching, ultimately leaving only the biodegradable materials on the target surface. To simplify multistep fabrication processes, wafer-scale transfer methods have also been developed [74]. These involve fabricating

Typically, these particles are composed of biodegradable materials, such as poly(lactic-co-glycolic acid) (PLGA) or chitosan. One of the main advantages of polymers is that they can be designed to
