Abstract
A system and method for using a sensor includes a first anode and cathode pair having a first non-zero voltage therebetween and an ionic liquid contacting the first anode and cathode pair. An output is provided that communicates a motion sense signal corresponding to a motion or pressure of the sensor in at least one direction that causes a change in a first ionic concentration gradient between the first anode and cathode pair.
Claims19
A sensor comprising:
- a first anode and cathode pair having a first non-zero voltage therebetween;
- an ionic liquid contacting the first anode and cathode pair, and
- an output communicating a motion sense signal corresponding to a first motion or a first pressure of the sensor in at least one direction that causes a change in a first ionic concentration gradient between the first anode and cathode pair.
A sensor comprising:
- a first anode and cathode pair having a first non-zero voltage applied, the first anode and cathode pair being oriented substantially parallel to a first direction;
- an ionic liquid contacting the first anode and cathode pair;
- a vibrational actuator configured to vibrate the ionic liquid in the first direction, and
- an output communicating a motion sense signal corresponding to a first rotational motion of the sensor in at least one rotational direction that causes a change in a first ionic concentration gradient between the first anode and cathode pair.
A method of measuring motion or pressure data, the method comprising:
- a) applying a first non-zero voltage to a first anode and cathode pair that is contacted by an ionic liquid thereby establishing a first ionic concentration gradient across the first anode and cathode pair;
- b) measuring a change in an electrical property across the first anode and cathode pair after a motion of the first anode and cathode pair, the ionic liquid, or a combination thereof.
