Researchers at King Abdullah University of Science and Technology (KAUST) and International Institute of Information Technology (IIIT) Hyderabad developed an ultra-low-cost, flexible, paper-based touch-mode capacitive pressure sensor using Do-It-Yourself methods. The sensor achieved high sensitivity and linearity in the 10-40 kPa range with a 15.85 ms response time, demonstrating its utility for wireless control in prosthetic hands.
Key insights
- High-performance touch-mode capacitive sensing can be achieved through low-cost, Do-It-Yourself fabrication methods using readily available materials.
- The touch-mode operation allows for a wide linear response range and high sensitivity (10-40 kPa), overcoming limitations of normal-mode capacitive sensors.
- Incorporating a saturation mode beyond the linear range provides mechanical robustness, preventing diaphragm damage under excessive pressure.
