Transient electronics represents a new class of technology whose key characteristic is that active elements physically/chemically disappear, at controlled rates and/or programmed times, via a number of possible mechanisms including hydrolysis, dissolution, de-polymerization, metabolic action, or disintegration. The mode and rate of this transience are sensitive to the properties of the environment, such as chemical or biological events, temperature, pressure, or light. Such transient behavior is completely different from the existing, traditional electronic systems that are designed to be functionally long-lasting, reliable, and invariant. Given the unique degradable, function-variable, and stimuli-responsive characteristics of transient electronics, such emerging technology offers compelling opportunities in the development of 1) resorbable medical implants (to avoid device retention and retrieval); 2) environmentally benign and disposable electronics (to minimize environmental footprints); 3) self-destructing safety/security systems; etc.
A broad range of materials proposed for transient/biodegradable electronics span from organic polymers (synthesized or naturally derived), to inorganic semiconductors (silicon, germanium, etc), interlayer dielectrics, metals and alloys, and hybrid materials. Demonstrated electronic devices/systems include CMOS, various sensors, radio frequency energy harvester, battery, and many others, targeting applications involving diagnostic/therapeutic monitoring, drug delivery, wireless signal/power transmission, electronic skin, etc. Various approaches integrating a variety of dissolvable biomaterials includes transfer printing, MEMS fabrication and semiconductor foundry compatible processing for advanced transient electronic system.
This symposium will cover a comprehensive range of biomaterials and degradable electronic systems. It will focus on the fundamental materials science, materials degradation kinetics, novel device systems, and fabrication techniques to integrate multifunctional biomaterials. Interdisciplinary topics related to physics, chemistry, materials science, and electrical engineering will shed important insights and inspire possible new areas for transient electronics.
