CHAPTER 8
Applications to Biomechanics and Impact
Biomechanics
The force controllability of human fingers and the impact responses of the arm and palm were evaluated with the LMM.

Impact
Impact responses of a bamboo sword and of an accelerometer, and the impact force on a ball dropping onto a water surface, were measured.

Actuators
The force generated by a voice-coil linear motor is measured as the inertial force of the levitated mass, to evaluate its electrical and mechanical characteristics in motion. Force was almost proportional to current, with high reproducibility over eight periods of reciprocating motion.
