Wearable Algorithms

An Overview of a Truly Multi-Disciplinary Problem

Guangwei Chen, Esther Rodriguez-Villegas and Alexander J. Casson, Imperial College, London, UK

This chapter introduces and comprehensively overviews emerging wearable algorithms for embedding in to wearable sensor nodes. We begin with an overview of some of the potential benefits of low power real-time signal processing in wearable sensors with a particular focus on increasing the operational lifetime. Measured results from a practical state-of-the-art sensor platform demonstrate and quantify the design trade-offs present and the potential system optimizations available. We then consider the theory behind wearable algorithms and highlight the key properties ...
