!!!Applications

Stretch Sensor can act like muscle contraction, and can be easily applied to any wearable design.

!!!Electrical Characteristics
[[http://www.merlinsystemscorp.co.uk/downloads/ssappnote1.pdf | datasheet here]]

Give the voltage and amperage ranges, and any other relevant electrical data.
Describe the electrical changes when the sensor senses whatever physical changes it senses.

!!! Pin Descriptions
It acts like a variable resistant, just plug the two end into the place where you need.


!!!Microcontroller Connections
Explain how to connect the sensor to a microcontroller or computer. Include a schematic and any other necessary diagrams. Make sure to include a list of every part in the schematic.

!!!Code Sample


!!!Typical Behavior

As the length of the Stretch Sensor alters so does it's resistance. For each centimeter of length change there is a resistance change of approximatly 400 Ohms/cm.
