| Abstract: | A novel approach for the realization of all elastomer based highly flexible capacitive tactile sensors and matrix with highly linear characteristics is presented. The capacitive tactile sensors and matrix consists of a microstructured elastomer dielectric layer sandwiched between two overlapping parallel flexible electrodes. The microstructured elastomer dielectric layer consists of an array of microstructures forming a strong bond with lamination layer. The normal pressure induced deformation in the microstructures is applied pressure magnitude dependent and which led to increase in capacitance. The proposed methodology produces a highly linear characteristics (Adj. R2: 0.998) over a broad applied pressure range (up to 250 kPa/40 N) with a uniform micro pyramidal-airgap across the entire sensor/sensor matrix. The developed sensors are highly flexible and robust from the structural point of view; therefore, conformable attachment is possible on various shapes. Figure 1 | ||
