Flexible Stretch Sensors

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:

• Robotics
• Biometric displacement reading
• VR Gloves and VR suits
• Physics applications and experiments
• Feedback sensor for air muscles

Flexible Stretch Sensors are sold with standard electrical terminals.
