Abstract
Provided herein is a multi-axis sensor including: a pair of electrodes positioned such that at least partial areas thereof face each other; an elasticity member having one of the pair of electrodes installed in its upper portion and another of the pair of electrodes installed in a lower portion; and a sensor unit electrically connected with the pair of electrodes, and configured to detect a change of capacitance value between the pair of electrodes and a change of resistance value of the elasticity member.
Claims13
A multi-axis sensor comprising:
- a pair of electrodes positioned such that at least partial areas thereof face each other;
- an elasticity member having one of the pair of electrodes installed in its upper portion and another of the pair of electrodes installed in a lower portion;
- and
- a sensor unit electrically connected with the pair of electrodes, and configured to detect a change of capacitance value between the pair of electrodes and a change of resistance value of the elasticity member measured using the pair of electrodes, so as to measure an external force applied to the elasticity member.
A method of measuring magnitudes of an external force applied to a multi-axis sensor comprising a first electrode and a second electrode embedded in a dielectric body, the method comprising:
- measuring a resistance value of the dielectric body using the first electrode and the second electrode;
- measuring a capacitance value between the first electrode and the second electrode;
- calculating a horizontal component of the external force based on a change of the capacitance;
- and
- calculating a vertical component of the external force based on a change in the resistance of the dielectric body.
