    Abstract: A fingerprint sensor-compatible overlay which uses anisotropic conductive material to enable accurate imaging of a fingerprint through an overlay is disclosed. The anisotropic conductive material has increased conductivity in a direction orthogonal to the fingerprint sensor, increasing the capacitive coupling of the fingerprint to the sensor surface, allowing the fingerprint sensor to accurately image the fingerprint through the overlay. In one embodiment, the overlay is configured to enclose a device which includes a fingerprint sensor. In another embodiment, the overlay is configured as a glove. Methods for forming a fingerprint sensor-compatible overlay are also disclosed.
