Abstract
A sensitive and small pointing device includes a substrate, a sensing member having at least one cantilever arm and a rubber member for shrouding the sensing member on the substrate. The rubber member may be deformed under an external force and induces the cantilever arm to produce strain which results in strain signal generation. The rubber member may produce greater dimensional change when being squeezed. The cantilever arm is resilient and may generate greater strain while receiving force from the rubber member. Hence, the pointing device may have higher sensitivity, produce greater strain and be made at a shorter height.
