“…In another example, Samsung's Galaxy Note 7 includes an infrared iris sensor, which allows biometric authentication on consumers' devices for security and access control [43]. Similarly, while until recently only a few devices came with fingerprint sensors [19], this technology has become increasingly more accessible for end-users. Goel et al [20] showcase how a hyperspectral sensor, previously used for research, can assist in a wider set of use cases.…”

Near Infrared Spectroscopy (NIRS) is a sensing technique in which near infrared light is transmitted into a sample, followed by light absorbance measurements at various wavelengths. This technique enables the inference of the inner chemical composition of the scanned sample, and therefore can be used to identify or classify objects. In this paper, we describe how to facilitate the use of NIRS by nonexpert users in everyday settings. Our work highlights the key challenges of placing NIRS devices in the hands of nonexperts. We develop a system to mitigate these challenges, and evaluate it in a user study. We show how NIRS technology can be successfully utilised by untrained users in an unsupervised manner through a special enclosure and an accompanying smartphone app. Finally, we discuss potential future developments of commoditised NIRS.

This paper implements 80x64 array high sensitive fingerprint sensor with the parasitic insensitive charge transfer circuit. The fingerprint sensor cell uses an active output voltage feedback integrator. The parasitic insensitive charge transfer circuit includes a differential amplifier and two switches to remove parasitic capacitance and transfer charge. The operation is validated by HSPICE for one-pixel and RTL simulation including logic synthesis for the full chip design on condition of 0.18µm typical CMOS process and 1.8V power. The voltage difference between a ridge and valley is about 215mV after 10 clock cycles and 367mV after 20 clock cycles. The maximum frequency of cell operation is 10MHz. The layout is performed by full custom flow for one-pixel and auto P&R for the full chip. The area of the full chip is 4943μm x 3943μm and the gate count is 542,000. The area of one-pixel is 50μm x 50μm. Pitch is 50µm and image resolution is 508dpi.
