Abstract: Control panel including a cover mounted on a support that is provided with a tactile pressing detection zone in which a force sensor that includes a pressure-sensitive zone is arranged behind a detection zone between the cover and the support so as to produce an electrical control signal when a user applies a determined tactile pressing force to the detection zone. The tactile pressing force is transmitted axially (X1) towards the sensitive zone via a spacer made of elastically compressible material interposed between the sensor and the cover. The spacer includes at least one compressible portion that defines a transversal top surface that bears against the cover and a transversal bottom surface that bears against the sensitive zone of the sensor. The top surface has an area smaller than the area of the bottom surface.

Abstract: Disclosed herein are novel contact sensors. The contact sensors disclosed herein include a conductive composite material formed of a polymer and a conductive filler. In one particular aspect, the composite materials can include less than about 10 wt % conductive filler. Thus, the composite material of the contact sensors can have physical characteristics essentially identical to the polymer, while being electrically conductive with the electrical resistance proportional to the load on the sensor. The sensors can provide real time dynamic contact information for joint members under conditions expected during use.

Abstract: A force sensing array includes multiple layers of material that are arranged to define an elastically stretchable sensing sheet. The sensing sheet may be placed underneath a patient to detect interface forces or pressures between the patient and the support structure that the patient is positioned on. The force sensing array includes a plurality of force sensors. The force sensors are defined where a row conductor and a column conductor approach each other on opposite sides of a force sensing material, such as a piezoresistive material. In order to reduce electrical cross talk between the plurality of sensors, a semiconductive material is included adjacent the force sensing material to create a PN junction with the force sensing material. This PN junction acts as a diode, limiting current flow to essentially one direction, which, in turn, reduces cross talk between the multiple sensors.
