Abstract
Impulse responses of freshly harvested skeletal muscle specimens are presented for the first time using an impact hammer. The mass-tissue assembly represents a single degree of freedom mass-spring-damper system with the mass end free to move. The specimens were extracted from one thigh of a freshly sacrificed pig of approximately three-month old. The sprung mass was 2.5 kg with a flat and a hip- borne indentation interface with the tissue. With the impact force exerted in the vertical z-axis of the mass, the accelerance exhibited resonances at around 25 Hz and 40 Hz. With horizontal x-axis impacts, a single resonance appeared at around 2 to 3 Hz with its peak magnitude almost half of the peak magnitude obtained from the vertical impact. The magnitude of impact and thickness of specimen seemed to have little effect on the resonance frequencies. The specimen thickness from 10 to 20 mm has no clear effect on the parameters extracted.
