Features:
- Stretch sensor
- As the sensor is stretched, resistance across the two leads decreases
- Length:
- Unstretched: 16 inches
- Stretched: 32 inches
- Width: 0.275 inches (7mm)
- Resistance: goes from approx 100K ohms when unstretched down to 40K ohms when stretched
- Easy to work with
- Connectors at both ends
- Made with high quality materials
- Flat design that's easy to mount against a flat surface or run around an object.
- Sew conductive thread or attach wires at both ends and measure the resistance across to tell how far the sensor has been stretched
Can this be cut down into smaller lengths? And if so, how do you make the electrical contact after cutting it down?
You can cut it. You\'ll have to pry the connector off and reattach it at the cut end. I have cut a bunch of these to get it to fit my project and it worked well.

C · 08/17/2021Is this a linear sensor? Is the change in stretching distance linearly proportional to change in resistance?
It\'s not a true linear sensor. The resistance increases when it is pulled because the particles get further apart when the material is stretched thin. You can measure how much the sensor is stretched more or less by measuring how high the resistance is. More stretched = more resistance. Calibrate the values before use to see if someone/something is stretching it or not. Values can vary from batch to batch so make sure to calibrate for the sensor you\'re using. It\'s great for measuring if it\'s stretched thin or hanging loose.
