ABSTRACT:
A sensor structure for attachment to the foot of an animal to continuously measure the pressure of the foot against a reactive surface. The sensor structure provides a small flat particularly configured piece of piezoelectric plastic, encapsulated to protect it and interconnected electrically with telemetry and analyzing apparatus. Plural sensors may be used in various parts of a foot to determine local pressures. The sensed pressure may be recorded and annunciated by various known means to aid analysis of foot and limb activity and general animal physiology.
