세미나 제목 : Transient Electronics - Lifetime Controlled Electronics for Biomedical Sensing and Treatment
Usual electronic devices in the industry require durability and reliability for long-term operation. Transient electronics, an emerging class of electronics pursuing the device systems all of whose materials physically/chemically disappear, assigns a new time frame to materials and devices: stable operation on a brief, temporary time scale. Transient electronic systems are of growing interest for future classes of bioresorbable implants, eco-friendly sensors, zero-waste devices with minimized hazardous waste streams, hardware-secure electronics and other applications. Such classes of electronics are of particular relevance in biomedicine, where they have potential for use in programmable drug delivery, temporary cardiac pacemaking and nerve stimulation, and sensors for medical therapy, diagnosis and monitoring.
Here we report on recent progress in dissolution chemistry of electronic materials, functional degradation of integrated devices, encapsulation strategy for lifetime control, and their biomedical applications. Hydrolysis kinetics of silicon, germanium, silicon oxide and nitride in various pH buffer solutions open the way to high- performance electronic materials in biodegradable form. Electronics of various active and passive components and their integrated circuit on a soft bioresorbable polymer provide biomedical implants interfacing to tissues and organs. Representative examples of biomedical applications include intracranial pressure monitors for traumatic brain injury, electrical stimulators for nerve and cardiac modulation, and drug delivery vehicles for cancer treatment.
