1. A heart activity sensor structure, comprising:
- a first layer comprising at least two printed electrodes on one side of a flexible substrate, the first layer being printed, the at least two printed electrodes being configured to be placed against a skin of a user in order to measure biometric signals related to heart activity;
a second layer comprising the flexible substrate, the flexible substrate being substantially non-conducting;
a third layer comprising a printed electrostatic discharge shield on an opposite side of the flexible substrate in relation to the at least two printed electrodes, the third layer being printed, the printed electrostatic discharge shield protecting the at least two printed electrodes from static electricity;
an insulation encompassing the third layer, the insulation comprising an electrically non-conducting material that provides electrical insulation between the second layer and the third layer;
at least two through holes in the second layer, the third layer, and the insulation; and
one or more insulated conductors coupling to the electrodes through each of the at least two through holes.

Abstract
A heart activity sensor structure includes a flexible substrate being substantially non-conductive, at least two electrodes printed on one side of the flexible substrate and configured to be placed against a skin of a user in order to measure biometric signals related to heart activity, and an electrostatic discharge shield printed on opposite side the flexible textile substrate, compared to the printing of the at least two electrodes, for protecting the at least two electrodes from static electricity.
