1. A load sensor, comprising:
a load sensing assembly configured to determine a force of a load attached to a device the load sensing assembly positioned between the device and a load, the load sensing assembly including:
a spring plate configured to deflect in a first direction when the force of the load increases,
a first sensor configured to apply a first electrical signal to a first conductive surface associated with the spring plate, the first sensor including a first antenna configured to receive a signal from the first conductive surface, wherein the first electrical signal is dependent on a distance between the first antenna and the first conductive surface, and
a sensor circuit configured to receive an input from the antenna representative of the distance between the first antenna and the first conductive surface.
