Transient electronics is a research field and academic concept focused on the design, fabrication, and application of electronic systems engineered to function for a specified period and then undergo intentional, programmed degradation or dissolution into environmentally benign constituents. This approach investigates novel materials, device architectures, and integration strategies that enable temporary electronic functionality, offering solutions for reducing electronic waste and facilitating applications requiring transient presence, such as biodegradable medical implants or temporary security devices.
