FLEXIBLE ELECTRONICS

A Fully Functional Auxetic Electronic System
Group-in-charge: Prof. Hongyu YU
In this project, we have the following missions:
1. Understanding from mathematics and mechanics of origami tessellations and addressing the technical challenges from electronics and manufacturing to facilitate the development of smart garments.
2. Developing the additive and micro-manufacturing for multi-functional and multi-scale devices (such as thermoelectric energy conversion devices) for monitoring human movement and health.
3. Developing the packaging technology for origami-inspired systems to get a fully functional auxetic (growable) electronic system for wearable applications.

Ultralight Sound Absorber
Group-in-charge: Prof. Hongyu YU
Focus Area: Public Health – To absorb noise
A novel ultra-light metamaterial for sound absorption based on Miura-ori tessellation structure, which exists an extremely low mass packing density with only 10.64 mg/cm3. This sound absorber, made from nanofibrous materials which is environmentally friendly and has good biocompatibility, has excellent soundproof function and can be widely used in humans’ daily life.
