Abstract
A thermal pattern sensor including a plurality of pixels arranged on a substrate. Each pixel has a pyroelectric capacitance formed by at least one pyroelectric material portion arranged between a lower electrode and an upper electrode. The sensor has an abrasion-resistance coating, located on the side opposite the substrate and including pillars embedded in an abrasion-resistance layer, the pillars having a thermal conductivity strictly higher than that of the abrasion-resistance layer. A high thickness of the anti-abrasion protection coating can be achieved with a high rate of thermal transfer through the latter.
