Abstract
Embodiments generally relate to assembly and methods for detecting force. A force sensor assembly may comprise a sense element, an isolation medium, a thin membrane, and a substrate. Typically, the sense element may be located adjacent to the substrate, the isolation medium may be located adjacent to the sense element, and the thin membrane may be located adjacent to the isolation medium. Generally, the thin membrane may be configured to provide a shield between an external medium and the isolation medium and transfer a force from the external medium to the isolation medium. In this manner, the isolation medium may be configured to transfer the detected force to the sense element. The sense element may electrically communicate the force data as output signals to the electrical traces on the substrate.
