1. The method of directly transducing the body activity waves from the body limbs, comprising the steps of:
- connecting a piezoelectric transducer to an elastic strip to form a transducer assembly,applying one said transducer assembly on each of the four (4) major body limbs, andconverting each of the transducer signals into unipolar voltage waveforms directly proportional to the activity energy they represent.

Abstract
Clamping a piezoelectric transducer onto the arm produces a signal whose integration with respect to time corresponds directly to the energy produced by the arm'"'"'s movement. By clamping four (4) such transducers onto the body, one on each arm and one on each leg, the total integration of the four (4) signals gives a measure of the total energy spent in motion by the body. The desired body energy spent can be displayed quantitatively by first converting the integrated signal into a pulse train, then counting the pulses, and then driving a display with the counter'"'"'s value.
