Abstract
The objective of this project is to develop a sensor-brain interface (SBI), which can restore the sense of touch and the sense of movement in a paralyzed hand. This proposal focuses on an ergonomic system for detecting force and vibration at the fingertips and movement at the finger joints. An ultra-low power, wireless, wearable sensor network solution is being developed. To improve functionality and circumvent the limitations of a discrete-component sensor node, an active sensor node will be powered by harvesting energy from the environment. Low-power sensors, including, but is not limited to, accelerometer, stretch sensor, and force sensor, will be used to develop a sensor network. A custom fully integrated detection circuit, consisting of 1) wireless power transmission, 2) multi-channel, low power analog front end, 3) wireless data transmission, and 4) an optional sensory encoder will be developed. The final outcome is a wireless, battery-free, wearable smart glove that can be utilized in the testing of in-vivo functionality of the SBI system.
