eBiometrics: Data acquisition and Physiological Sensing

Abstract

Biometric sensing has critical challenges in both mechanical design as well as sensor selection. The main issues however lie in the signal acquisition (accuracy and reproducibility) and signal processing to find the derived physiological value and at what ultimate accuracy. The association with biological parameters of clinical interest are under the influence of external factors. The external factors include electromagnetic impacts which can modify the outcome of the signal processing or may reset the operational processes of the device to a state of disorder. It is imperative to consider all factors contributing to the accuracy and validity of the output.
