Abstract
A micromechanical contact load force sensor is disclosed. The force sensor comprises an array of capacitive load cells on a substrate. The force sensor is able to sense high loads, on the order on 10.sup.9 N/m.sup.2, and distribute the load over a suitable number of the cells of the array while minimizing crosstalk between adjacent cells. The force sensor is useful in biological and robotic applications.
