Abstract
The invention relates to a skin print sensor () comprising, on a supporting substrate, a plurality of elementary acquisition cells (), each of which includes: a reading node (SN); a first photoelectric or pyroelectric conversion element (PYR) having a first electrode that is connected to the reading node (SN) as well as a second electrode that is connected to a control node (CMD) of the cell; and a third electrode (EL) that is connected to the reading node (SN), is coated with a dielectric layer and is designed to form a capacitance along with the skin of a user; in each cell of said sensor, the control node (CMD) is designed to receive a control signal that initiates reading of a value on the reading node (SN), said value representing the capacitance formed between the third electrode (EL) and the user's skin.
