Programmable Fingerprint Emulator

This proposal is for the development of a technology apparatus which can dynamically synthesize a mechanical fingerprint pattern, from an electronic image or from a computer-generated artificial pattern, onto a 2-dimensional pliable surface whose surface height is modulated by protrusions in the z-axis direction. When mechanically applied to a fingerprint sensor-under-test, the synthesized modulated surface appears to be a human fingerprint. Thus, the instrument can be utilized to apply all sorts of pre-programmed, standardized, controlled and/or experimental fingerprint patterns to a variety of sensors-under-test. Some of the key parametric attributes of this technology are: greater-than-500dpi resolution, large contiguous active area (3.2¿x2.0¿), up to 80 um of z-axis displacement, 8-bit resolution for height displacement, fast response time, fully computer-controlled, and compatible with all known fingerprint sensing technologies.
