US 2008/0184819 A1 · CAPACITANCE TYPE SENSOR

Abstract

A capacitance type sensor includes a first flange having four flexible portions and fixed to a base 300; and a second flange having four flexible portions and being opposed to the first flange. A connecting shaft standing at the center of each flexible portion of the first flange is connected to a connecting shaft standing at the center of each flexible portion of the second flange. A pair of electrodes E11 and E12; a pair of electrodes E21 and E22; a pair of electrodes E31 and E32; and a pair of electrodes E41 and E42 are fixed on the upper face of the base 300. The sets of pairs of electrodes, flexible portions of the first flange, flexible portions of the second flange, and connecting shafts are arranged around the Z-axis at regular angular intervals of 90 degrees at the same distance from the Z-axis.

Dependent claims

A capacitance type sensor characterized in that the sensor comprises:

a pair of electrodes disposed on a plane;
a first flexible portion being opposed to the pair of electrodes so as to cooperate with each electrode to form a capacitance element;
a first member having the first flexible portion;
a second member having a second flexible portion being opposed to the first flexible portion;
and
an interconnecting member interconnecting the first and second flexible portions, and
the sensor detects a force parallel to the arrangement of the pair of electrodes on the plane and a force perpendicular to the plane on the basis of changes in the capacitance values of the capacitance elements respectively corresponding to the pair of electrodes.
