Abstract (en)
[origin: WO2018130672A1] The invention relates to a compensated pressure or force sensor, especially for temperature, characterised in that the sensor comprises: a. a substrate (401); b. on one side of the substrate, a first assembly of multilayer nanoparticles (200) between two electrodes; c. on the same side of the substrate, near the first assembly, a second assembly of monolayer nanoparticles (100) between two electrodes; d. an electronic circuit capable of measuring the variation of an electrical property of the first and second nanoparticle assemblies and combining said measurements. The invention also relates to a touch screen using such a sensor.
