  • These particular sensors were designed to be trimmed to fit. I have cut dozens of them in half to fit my application. The top of the sensor has 2 traces that are not connected. When you press down on the sensor you are pushing the top layer into the bottom layer, which has a coating of conductive ink. The more you press, the more surface area of the bottom layer comes into contact with the traces and the lower the resistance becomes. Cutting the sensor doesn’t interfere with any of this.

  • You need to use the sensor in a voltage divider circuit or an op-amp circuit. Check the datasheet for more info.
