Abstract: A compact force measurement system having high sensitivity and a wide dynamic range. A polymer transducer is capable of measuring static, dynamic and transient force changes in tension and compression using changes in optical properties at the molecular level of a pre-stressed polymer or birefringent crystalline material under a loaded condition. A force sensing linkage acts as a load sensor which measures both compression or tension type forces. The transducer is capable of directional force, pressure, and acceleration measurements and is extremely accurate for measuring small-force levels. Since the force transducer of the present invention is based upon optical techniques it is relatively immune to electronic noise and allows measurement of rapidly changing loads. The invention can be miniaturized to accommodate a wide variety of measurements requiring miniature force and/or pressure measurement devices.
