Smart Sensor (SS) electrodes and transducers connect to the TEL100M-C amplifier/transmitter and can generally record biopotentials and other signals for up to 24 hours. Each SS28 heel/toe strike transducer incorporates two force sensitive resistor (FSR) sensors designed for attachment to the sole of a shoe. Typically, one FSR is placed (taped) under the heel and the other is placed under the toe. The FSRs indicate the precise moment of pressure placed on the heel and toe as the subject walks. The heel/toe strike data is encoded onto a single analog channel; the heel strike results in a [-1V] signal and the toe strike results in a [+1V] signal. If heel and toe strike timing is required for both feet, two TSD111 transducers are required.
The SS28 comes equipped with a 7.6-meter cable and is designed for direct connection to the HLT100C module.???
Specifications mirror the TSD111 transducer.
