Abstract:
1. A contact-force sensor package comprising: an elastic layer comprising a side that contacts a source of a contact-force; and a substrate layer adhered to the opposing side of the elastic layer to the side that contacts the source of the contact-force, wherein a cavity that is not adhered to the elastic layer is formed in the substrate layer; the substrate layer further comprising: a cantilever beam disposed in the cavity, separated from the elastic layer and deformed due to the contact-force; a pillar extending from a free end portion of the cantilever beam to the elastic layer and transferring the contact-force from the elastic layer to the cantilever beam; where the substrate layer, the cantilever beam and the pillar are a single unitary piece; and a deformation sensing element for generating an electrical signal that is proportional to a degree of deformation of the cantilever beams; wherein an end portion of the pillar contacts a side of the elastic layer that is opposed to the side that contacts a source of a contact-force.
