A pressure sensitive electrically conductive composition comprises a contained quantity of magnetite particles, wherein the quantity of magnetite particles includes a distribution of particle sizes between sub-micron and tens of microns, and wherein the magnetite particles have a plurality of planar faces, adjacent planar faces connected at a vertex, the particles each having a plurality of vertices wherein the magnetite particles are irregular in shape and have a low aspect ratio.

Provided is an electromagnetic induction potentiometer adaptive for full-stroke detection, including a movable element configured to obtain an input for position change, a permanent magnet attached to the movable element, a magnetic induction sensor configured to sense positions of the permanent magnet and generate an initial potential signal, and an full-stroke adaptive output adjusting unit configured to collect the initial potential signal and adaptively adjust the initial potential signal to an actual potential signal corresponding to a full stroke of position changing of the movable element.

In one example a bend sensor is disclosed. The bend sensor extends into a media tray. The bend sensor has a tip where a deflection amount of the tip indicates a media parameter.

Provided is a pressure-strain sensor including a graphene structure having a three-dimensional porous structure, planar sheets provided on a surface of the graphene structure, and a polymer layer configured to cover the graphene structure and the planar sheets, wherein each of the planar sheets contains a transition metal chalcogenide compound.

A resistance substrate contains a substrate and a resistance part that is formed on an upper surface of the substrate by printing. The resistance part is formed into an arc shape (a C shape) so that a width of the resistance part continually changes. The resistance part is formed so that a part having a narrow width becomes thick and a part having a narrow width becomes thin.

A pressure sensor includes a variable resistance portion, and a first electrode and a second electrode. The variable resistance portion includes a conductive foam elastomer material. When pressure is applied to the variable resistance portion, the variable resistance portion is compressed in accordance with the pressure. As the compression amount increases, the electric resistance of the variable resistance portion decreases. The first electrode and the second electrode are configured to contact with the variable resistance portion at a location having an interval of 0.5 mm or greater with each other, therefore being electrically connected via the variable resistance portion.
