Abstract: A foot pad device includes a foot pad, force sensors that provide force data, sensor electronics coupled to the force sensors, and a processor. The foot pad includes a ball region configured to be located under a ball of the foot of the user or a heel region configured to be located under a heel of the foot of the user. At least a portion of the force sensors is located in the ball region or the heel region of the foot pad. The sensor electronics include a flexible circuit with force sensor connection paths adapted to transmit force data from the force sensors and are configured to condition the force data to be within a conditioned force data range. The processor is configured to calculate a weight value based on the conditioned force data, a gain value, and an offset value.
