An Improved Soft Dielectric for a Highly Sensitive Capacitive Tactile Sensor

摘要: This paper presents a novel capacitive tactile sensor that is capable of making highly accurate measurements at low pressure levels, while also being functional within wide range pressure. Many researchers have concentrated on sensing applied using methods, such as piezoresistive, optoelectronics, and piezoelectric technologies; but very popular approach in recent years uses capacitance-based sensing. However, most sensors, due to the properties their dielectrics, remain limited by hysteresis narrow ranges sensitivity. Our overcomes these restrictions because improved soft dielectric we constructed. features double-stage microstructure, allowing it be sensitive still able measure The silicone used construct doped with high permittivity nanoparticles enhance response sensor. Furthermore, considering complexity dielectric’s construction, our fabrication process relatively simple. In this paper, describe design present results sensor’s performance.
