DERMIS: Toward a Fully-Integrated Large-Area High-Resolution Tactile Slip Sensing Solution

This paper presents a pathway toward realizing electronic skins with on-chip embedded slip detection through large-area thin-film transistor (TFT) technology with integrated capacitive shear sensors. It discusses end-to-end implementations optimized for TFT integration – from the sensor to the encoding of the slip. Enabled by the opportunities offered by an integrated solution, we envision next-generation slip sensors in prosthetics and robotics applications to achieve more human-like performance due to its higher sensing spatial resolution, reduced slip detection latency, lower system power consumption, thinner and more flexible form factor, improved ease of use, and lower cost. We propose to use a capacitive slip detection sensor integrated on a TFT substrate with embedded electronics. The paper describes and shows the results of the initial prototype of our proposed DERMIS system.
