ABSTRACT:
A system operable to measure the time varying forces transmitted by a body and to combine the forces transmitted by different parts of the body. The system can be employed to measure physiological forces associated with motion of the body such as the gait of humans or animals. It can also be employed to measure forces internally generated by the body at rest such as ballistocardiographic and posture control forces. The posture control forces can be used as a measure of lameness. The Fourier transform of the force ballistocardiogram and posture control forces are found to contain information related to physiological condition. In some configurations the system employs ceramic capacitors as piezoelectric force transducers in a special circuit. The use of ceramic capacitors as pyroelectric bolometers is also discussed.
