Synthetic Tactile Sensing For Prosthetic Fingers

Supervisor: LEUNG Suk Wai Winnie / ISD
Student: WONG Tat Hang / CPEG Course: UROP1000, Summer

This project is part of Project SPARTHAN1, started by students in HKUST and Politecnico di Milano, aimed at providing
affordable 3D printed myoelectric prostheses to amputees. Project SPARTHAN has designed a mechanical hand, control
electronics and myoelectric signal processing algorithms. To continue developing this project, an artificial fingertip with
synthetic tactile sensing was needed to allow amputees to feel with their prosthetic fingers and to enable prosthetic
fingers to grab delicate objects using tactile feedback. This design report documents the process of manufacturing a low-
cost (22 HKD), lightweight (3g), waterproof and 3D printed fingertip capable of sensing temperature and applied forces
up to 200N.
