sensor for multi-touch and force detection based on EIT
technology was developed. A novel design of a sensor material made of
a porous elastic polymer and ionic liquid was proposed.
The proposed conductive flexible materials combining elastic
porous structures and conductive liquids provide continuous,
linear changes in impedance with respect to touch forces.
A deep learning scheme PSPNet based on MobileNet was
adopted to postprocess the originally reconstructed images to
improve the performance of tactile perception. By using this
data-driven method, we can improve the spatial resolution of
the tactile sensor to achieve a single-point position detection
error of 7.5±4.5 mm without using internal electrodes.
