Abstract
A flexible capacitive tactile sensor is provided. The flexible capacitive tactile sensor may include a first flexible electrode layer, a second flexible electrode layer, and an ion gel thin film dielectric layer disposed between the first flexible electrode layer and the second flexible electrode layer. A first electrode array is disposed on the first flexible electrode layer. The first electrode array may include m series-connected electrodes parallel to a second direction. A second electrode array is disposed on the second flexible electrode layer. The second electrode array may include n series-connected electrodes parallel to a first direction. The first electrode array and the second electrode array may be disposed opposite to each other, and the first direction may be different from the second direction. The first electrode array, the second electrode array, and the ion gel thin film dielectric layer may form m×n electric double layer capacitors.
