Title:
MICROSENSOR WITH INTERDIGITATED ELECTRODES
Document Type and Number:
WIPO Patent Application WO/2023/111344
Kind Code:
A1
Abstract:
The invention relates to a microsensor (210) comprising a first electrode (211) and a second electrode (212), each electrode comprising a plurality of parallel traces (222), each trace comprising one connected end and one free end, each trace extending from a connector strip (223), said connector strip connecting the traces by the connected ends thereof, the traces of the two electrodes being offset and mirror-symmetrical such that said traces of the two electrodes are interdigitated and comprise, between each pair of interdigitated traces, an assembly of nanoparticles in a ligand, characterised in that each trace (222) comprises at least one change of direction as it extends away from the connector strip (223).
