Flexible Stretch Sensors
The Stretch Sensor is a unique component that changes resistance when stretched. When relaxed the sensor material has a nominal resistance of 1000 ohms per linear inch. As the stretch sensor is stretched the resistance gradually increases. When the sensor is stretched 50 % its resistance will approximately double to 2.0 Kohms per inch.
The stretch sensor is a new way to measure stretch, displacement and force. The sensor is a flexible cylindrical cord .060-.070 in diameter, with spade or ring electrical terminals at each end.
The sensor above measures 4 inches long, not including the electrical
terminals and only .060 inches diameter. The chart below illustrates the approximate resistive response of the stretch material.
Each sensor length requires a different force for
50% elongation. As an example to lengthen a 6" sensor to 12" would require a
force of approximately 420 grams.
Some applications for the Stretch Sensor are:
- Biometric displacement reading
- VR Gloves and VR suits
- Physics applications and experiments
- Feedback sensor for air muscles
