Title: Highly durable soft electronics with tactile sensors

Abstract:

Soft electronics are gaining significant attention in healthcare, robotics, and medical devices as they surpass the limited functionality and form of conventional rigid electronics. Especially, soft electronics with high flexibility and stretchability can make conformal contact with the human skin or robotic body, enabling the detection of tactile stimuli from human or robots. However, the current sensing technologies and device durability are not yet fully optimized for practical use. In this talk, we will introduce advancements in the following areas to address these challenges:

1. Tactile sensors with high sensitivity and low hysteresis: We have explored soft materials and structural approaches to improve sensitivity to pressure, lateral strain, and bending. Additionally, high adhesion from strong interactions of nanomaterials has contributed to lower hysteresis.
2. Highly durable electronic skin with tactile sensing: To increase the mechanical durability of devices, we fabricated Ferris wheel-shaped islands that show high and strong interfacial stability. Our electronic skin withstands repetitive stretching, twisting, and poking.
3. Bioinspired soft electronics: We have developed innovative ways to create soft electronic devices inspired by biological structures and principles, focusing on advanced device functionality. It was fabricated through 3D printing technologies.

This talk will provide practical solutions for soft electronics.
