Assistive Rehabilitation Sensor Technology for PwD

Pressure Sensitive Adhesive-based Flexible Strain Sensor Tape

Objective

• A 'strain sensor' quantifies a specimen's mechanical deformation and finds applications from conventional structural health monitoring to recent wearable electronics. This project aims to design a three-layer pressure-sensitive adhesive-based flexible strain sensor with a copper electrode atop and thickness-controlled adhesive coating at the bottom to reduce the hindrances in strain transmission. The developed sensor tape will be optimized to achieve a higher gauge factor with a demonstration in real-time applications such as human activity monitoring.

Description

• Develop a 3-layer PSA tape flexible strain sensor by coating the thickness-controlled adhesive coating at the bottom and the copper electrode on top of the sensor; study the strain sensor's electrical conductivity, adhesive bond strength & piezo-resistive characteristics., Demonstrate for real-time wearable electronics applications such as tactile sensing and human activity monitoring.

Impact

• The strain sensor can read the human body movements for rehabilitation purposes for paralyzed patients. Further, it can be used to interpret the sign language into a voice for speech-difficulty people and make a bio-prosthetic human body. This can reduce the dependency on other people, and they can communicate and move independently.
