Research focus: Eco-manufacturing of buidegradable/recyclable soft electronics
Soft electronics represents a technology that has a huge potential in making impacts in a wide range of fields like defense, energy, and healthcare. With rapid increase of electronic devices that have decreasing lifetime in use, three important issues have emerged: (1) a huge amount of waste from used electronics, (2) rapid consumption of scarce elements to manufacture new electronic devices to keep up with the demand, and (3) the enormous energy consumed to manufacture these electronic devices.
My current research focuses on the development of major components of soft electronics such as substrate and dielectric material, using biodegradable and environmentally benign materials. One goal is to develop thin film substrates that can replace the existing synthetic, non-biodegradable fossil fuel based films. Substrates produced using different techniques will be evaluated for enhanced optical properties, thermal stability, and tensile and bending properties which are relevant to the operation and stability of soft electronic devices. Experiments will also be designed to fabricate soft and stretchable thin film substrates that can mimic the tensile stress- strain properties of human skin for applications in wearable devices. Another goal is to develop biopolymer based dielectric material with high dielectric constant. For this purpose, potential methods will be investigated to increase and adjust the permittivity of the dielectric composites. The expected aftermath is to produce biodegradable and sustainable soft electronics components in small scale that can transform into industrial scale manufacturing in future.
