Layers of a Biometric Sensor

Coverlay: TPU or printed encapsulate. Reliefs for electrodes and terminations.

Carbon Overprint: An added layer of wear resistance. Optional for some constructions.

Electrode: The electrode can be made using silver, silver chloride, carbon, or a proprietary ink blend.
Conductor: The conductor is made using silver or carbon traces.
Carbon Underprint: Added to reduce moisture transfer through TPU. Optional for some constructions.
Base Film: Typically a flexible and stretchable TPU film with hot-melt adhesive.
Fabric: The fabric layer is optional. Adding a fabric layer is ideal for non- permanent applications.
