This paper describes a double-layer simplified sensor unit based on the interesting electromechanical properties of MWNT mixed by polymer composite and PVDF films, which is envisaged to imitate the distributed tactile receptors of human hands so as to help the disabled to recover the basic tactile perception. This paper shows the fabrication and performance research of such a new piezoelectric-piezoresistive composite material which indicates a promising .application in prosthtic hand. DOI…

A Fuzzy Logic Based Piezoresistive/Piezoelectric Fusion Algorithm for Carbon Nanocomposite Wide Band Strain Sensor
TLDR
The developed PPF methods were verified with experimental data at different dynamic frequencies that were obtained from existing literature and a high degree of accuracy was achieved by the subtractive clustering PPF’s FISs algorithm.
E-Skins: Biomimetic Sensing and Encoding for Upper Limb Prostheses
TLDR
This review will present the physiology of the receptors that encode tactile, thermal, nociceptive, and proprioceptive information and the state of the art in e-skin design and deployment in closed-loop applications that demonstrate the benefits of sensory feedback for amputees.
