Abstract

A combination of sensors, including solid-state gyros and force-sensitive resistors, are mounted in an insole suitable for insertion into a shoe. Data from the sensors is recorded by an in situ Programmable Interface Controller (PIC), logged into on-board EEPROM/Flash memory and relayed to a base station computer via a miniature telemetry transmitter triggered by RFID tagging. Software then uses this data to compute the cadence and ankle power of the subject, as well as other parameters, in order to analyze and assess the gait and activity of the subject.

Claims

1. a device comprising a soft, flexible insole, means for measuring acceleration and rotation of said insole embedded within said insole, means for capturing and storing data of acceleration and rotation output from said measuring means, and means for relaying data captured by said capturing and storing means to an external data receiver.
