Valve systems include at least one component comprising a conductive material and at least one inductance-to-digital converter (LDC) configured to wirelessly sense a position of at least a portion of the conductive material. The valve system is configured to determine at least one force applied to a portion of the valve system based at least partially on the position of the at least a portion of the conductive material. Methods of determining a force associated with a valve system include wirelessly sensing a position of at least a portion of the conductive material with the at least one inductance-to-digital converter (LDC) sensor and determining a force applied to a portion of the valve system based at least partially on the position of the at least a portion of the conductive material.
