A dynamometer for nature's engines
IEEE Instrumentation & Measurement Magazine, 2019Muscle is an amazing natural thermodynamic engine that converts chemical energy into mechanical work. Each muscle twitch is ‘sparked’ by an electrically-released pulse of calcium ions, which trigger force-development and cell shortening, at the cost of energy and oxygen, and the dissipation of heat.

Accuracy of the Jamar Dynamometer
Journal of Hand Therapy, 1993The purpose of the study was to check the calibrations of six Jamar dynamometers. Five handle positions were tested for each instrument, with the application of seven different external forces, from 5 kg to 60 kg. Between two testers the repeatability was also evaluated.

Transactions of the American Institute of Electrical Engineers, 1951
SINCE THE ANNOUNCEMENT of the magnetic fluid by J. Rabinow1 in 1948, several manufacturers have been producing magnetic fluid clutches for use primarily in servomechanisms. Though some manufacturers also have produced designs for breaking service, the author knows of no instance where the magnetic fluid has been used for absorption-dynamometer ...

A dynamometer for biomechanical use
Journal of Biomedical Engineering, 1979A dynamometer has been designed for measuring isometric forces in human body limb segments. The dynamometer constrains the chosen segment, and measures two orthogonal components of the force reaction between the segment and the dynamometer in a plane perpendicular to the long axis of the segment, plus the torque reaction parallel to the long axis of ...
