Architecture
The Fidelica fingerprint sensor carries the methodology of elegant design from the level of the sensing element all the way to the finished product architecture.
In total, the sensor is constructed only of several laminated films combined with two ASICs, which are used for driving, sensing, and multiplexing of the passive array.
This results in a sensor that is remarkably thin, at well below a half millimeter in height.
These ASICs manage data flow to host devices, sending the sensor image in a simple, SPI-compatible signal.
The clean overall design leads to a sensor that is very different and in many ways, better than the fingerprint sensor competitive landscape.
Benefits
The elegant product architecture employed in Fidelica's fingerprint sensor leads to a sensor that is uniquely:
- Inexpensive. An uncomplicated combination of straightforward components, utilizing a minimum of silicon, results in a touch sensor at an unparalleled price point.
- Robust. The sensor is, by nature of the polymer films, flexible. It is fully compatible with ISO standards for bending and torsion in smart cards. The simplicity of construction adds to the product-level robustness.
- Versatile. A modular approach to design results in a fingerprint sensor that is well suited to modular improvements and added functionality.
