Scalable And High-Performance Pressure Sensors For Wearable Electronics

Patent Status

Brief Description

This invention are flexible pressure sensors with high sensitivity, broad working range and good scalability are highly desired for the next-generation of wearable electronic devices. Embodiments include large-area compliant and cost-effective processes to fabricate high-performance pressure sensors using mesh-molded periodic microstructures and printed side-by-side electrodes. 

Suggested uses

Wearable human-interactive devices can improve our quality of life and health. Flexible pressure sensors, as an important element of human-interactive devices, are of great interest and have a wide range of applications such as continuous health monitoring, personal diagnostics, robotics, prostheses, etc.

Advantages

These fabricated pressure sensors advantageously exhibit low operating voltage (e.g., 1 V), high sensitivity (e.g., 23.87 kPa^-1), low detection limit (e.g., 7.4 Pa), fast response/recovery time (e.g., 25/20 ms), and excellent reliability (e.g., over 10,000 cycles). Additionally, the sensors show broad working range (e.g., 7.4~1,000,000 Pa), high tunability, large-scale production feasibility, and significant advantage in creating sensor arrays with self-defined patterns.
