Force dependant on actuation interface, mechanics, touch location, and measurement electronics. The Ohmite FSR series exhibits the unique characteristic of dynamic resistance related to the amount of applied force. In general, the more force applied to the surface of the sensor, the lower the resistance. The resistance change is inversely proportional to the applied force. Typical force-sensing resistors are characterized for Human- Machine Interface (HMI) or Machine-Machine Interface (MMI) applications with a sensing range from circa 20g to 5Kg. Specific device character- istics will depend on the size, shape and materials used in construction. Force-sensing resistors are intended for applications where a delta in applied force is to be detected. They are not intended for high accu- racy or specific weight measurement applications.
