Claim 17:
18. A tactile sensing system, comprising:
an excitation circuit, configured to output a sensing excitation signal to one or more electrodes in a first flexible electrode layer and a second flexible electrode layer;
a flexible capacitive tactile sensor comprising a first flexible electrode layer, a second flexible electrode layer, and an ion gel thin film dielectric layer, and configured to determine a touch sensing signal based on the sensing excitation signal and a change in a contact area between at least one of the first flexible electrode layer or the second flexible electrode layer and the ion gel thin film dielectric layer,
a signal detection circuit, configured to receive a touch sensing signal from the flexible capacitive tactile sensor; and
a signal processor, configured to process the touch sensing signal and determine a touch position and a touch strength.
