An apparatus includes a flexible substrate; at least one sensor mounted on the flexible substrate arranged to provide an electrical output signal dependent upon a first parameter; and at least one conductive trace provided on the flexible substrate arranged to provide a direct current path to the at least one sensor and having an electrical property dependent upon a second parameter and arranged to provide an electrical output signal indicative of the second parameter.

Apparatus for sensing comprising a flexible substrate

An apparatus for sensing radiation is provided. Certain examples provide an apparatus including: a first layer including a sensor, wherein the sensor is configured to be responsive to changes in an electric field in the vicinity of the sensor; a second layer including a substrate configured to produce charge carriers in response to incident radiation; and a third layer including a plurality of electrodes, wherein the plurality of electrodes are configured to be selectively addressed during a readout operation of the sensor. Certain examples, relate to an apparatus for sensing X-rays or sensing neutrons including a graphene field effect transistor.

Apparatus for sensing radiation

A charge-carrier Hall-effect sensor comprising: a semiconductor or a semimetal layer; a pair of electric current contacts in electrical contact with the semiconductor or semimetal layer and separated in a first longitudinal direction along a first electric current channel; a pair of voltage contacts in electrical contact with the semiconductor or semimetal layer and separated in a second transverse direction, orthogonal to the first direction, and positioned on either side of the electric current channel; an electrically insulating layer underlying the semiconductor or the semimetal layer; and a ferromagnetic layer underlying the electrically insulating layer comprising at least one region having a magnetic moment with a component perpendicular to a plane comprising the pair of electric current contacts and the pair of voltage contacts.
