Description
14" long flexible cylindrical cord
Measures stretch, displacement and force
Changes resistance when stretched
The Images Scientific 14" Flexible 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 to 150% of its original length (14" X 150% = 21"), 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 with hook electrical terminals at each end. The sensor measures 14 inches long, not including the electrical terminals, and only .060 inches diameter!
Applications for the Images Scientific 14" Flexible Stretch Sensor:
This sensor worked really well, it came in pretty quickly. Very slight hysteresis, though I think it is more mechanical than electrical (it stretches slightly quicker than it returns to un-stretched length, though not visually perceptible, you see a little more lag in return.) Though it is not perfectly linear with stretch length, it worked fine being approximated as linear. Overall, the sensor performed its job very well, and was reliable and easy to use. I think that the price was a little bit high for what it likely cost to produce, but at the same time I would buy it again.
