AI Article Synopsis
- This paper presents a new type of triaxial capacitive force sensor designed for subdermal implants in fingertips and palms, aimed at enhancing tactile sensing for people with paralyzed hands.
- The sensor is made with biocompatible fused silica glass that houses four capacitors and can integrate additional electronic components for a complete tactile sensing system.
- When tested on a human palm, the sensor successfully detects common hand movements like squeezing and picking up objects, demonstrating its practical application.
Article Abstract
This paper reports a microfabricated triaxial capacitive force sensor. The sensor is fully encapsulated with inert and biocompatible glass (fused silica) material. The sensor comprises two glass plates, on which four capacitors are located. The sensor is intended for subdermal implantation in fingertips and palms and providing tactile sensing capabilities for patients with paralyzed hands. Additional electronic components, such as passives and IC chips, can also be integrated with the sensor in a hermetic glass package to achieve an implantable tactile sensing system. Through attachment to a human palm, the sensor has been shown to respond appropriately to typical hand actions, such as squeezing or picking up a bottle.
