Abstract
Examples for force-sensing elements are disclosed. An example method for forming a force sensor includes printing a suspension of a hollow-sphere conductive polymer in a liquid carrier over an electrode pair on a substrate, evaporating the liquid carrier, and encapsulating the electrode pair and hollow-sphere conductive polymer to form a force sensor.
Claims20
A method, comprising:
- printing a suspension of a hollow-sphere conductive polymer in a liquid carrier over an electrode pair on a substrate;
- evaporating the liquid carrier;
- and
- encapsulating the electrode pair and hollow-sphere conductive polymer to form a force sensor.
1 more element
A sensor array, comprising:
- a plurality of electrode pairs each comprising a first electrode and a second electrode in an interdigitated arrangement on a first layer;
- a layer of a hollow-sphere conductive polymer in contact with the first electrode and the second electrode and bridging a gap therebetween;
- and
- an encapsulating material encapsulating each electrode pair, such that a gap without the hollow-sphere conductive polymer is present between each adjacent electrode pair.
