Key result
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.

Supports accessible microforce sensing in animal muscle studies; leaves open extension to cardiovascular myofibril research.
Fearn et al. (1993) studied this question. Optical fiber force transducer was evaluated on Force measurement of skeletal muscle myofibrils. 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.
