A newly developed optical fiber force transducer successfully measures passive and contractile forces of skeletal muscle myofibrils up to 200 micrograms with 1 microgram resolution.
The development of an optical fiber transducer provides a simple, inexpensive, and high-bandwidth method for measuring microgram-level forces in skeletal muscle myofibrils.
A force transducer has been developed for use in force measurement of skeletal muscle myofibrils. The transducer is suitable for measurement of passive and contractile forces in a range up to 200 micrograms, with 1 microgram resolution. It is based upon the operating principle of the deflection of an optical fiber of known compliance, sensed by the differential illumination of two phototransistors. Attractive features include ease of operation and specimen mounting, high bandwidth, adaptability for different force ranges, and simple and inexpensive construction.
