摘要： A printed temperature sensor (10) comprising a substrate (1) with an electrical circuit (2) comprising a pair of electrodes (2a,2b) separated by an electrode gap (G). A sensor material (3) is disposed between the electrodes (2a,2b) to fill the electrode gap (G), wherein the sensor material (3) comprises semi-conducting micro-particles (3p) comprising an NTC material with a negative temperature coefficient (NTC), wherein the micro-particles(3p) are mixed in a dielectric matrix (3m) functioning as a binder for printing the sensor material (3); wherein the micro-particles (3p) contact each other to form an interconnected network through the dielectric matrix (3m), wherein the interconnected network of micro-particles (3p) acts as a conductive pathway with negative temperature coefficient between the electrodes (2a,2b).

摘要： The present disclosure relates a printable NTC material and to a method of manufacturing the printable NTC material. The printable NTC material particles. The particles comprising a spinel phase, preferably a C-spinel phase, having a general formula M 3 O 4 comprising at least a first metal M I that is manganese (Mn) and second metal M II that is nickel (Ni). In addition the particles includes nickel oxide (NiO) phase. The printable NTC material can be dispersed in a printable NTC ink comprising a dispersant, from which a NTC product, e.g. a thermistor, can be formed, e.g., after drying of the dispersant. Optionally, the spinel phase comprises a further metal M III . The weight fraction of nickel oxide (NiO) with respect to the overall mass of the printable NTC material is preferably in a range between one and twenty weight percent.
