Abstract

Capacitive force-measuring device based load sensing platform is disclosed. In one embodiment, a load sensing platform includes a sensor surface to have one or more capacitive force-measuring devices arranged in an array, a base surface placed on top of the sensor surface to provide contact surface of a load applied to the load sensing platform, and a control module to process data of the one or more capacitive force-measuring devices when the load is applied to the base surface. The load sensing platform may include a communication module of the control module to communicate the weight of the load or the position of the load through a wired channel and/or a wireless channel. The load sensing platform may further include an alert module of the control module to generate an alert signal when change in the position of the load exceeds a threshold value.
