Sensium: A 1V micropower SoC for vital-sign monitoring

This paper describes the main design components and methodology priorities for development of the Sensium system-on-chip for wireless body sensor networks. The device is targeted at vital-sign monitoring and related medical applications.

The SoC integrates an ultra-low-power wireless ISM band transceiver, hardware MAC, microprocessor, I/O peripherals, memories, 10b delta-sigma, analog-to-digital converter and custom interfaces.

The chip is implemented in 0.13 um CMOS and has a 16 mm² footprint. It operates from supply voltages as low as 0.9V and is part of a fully disposable body patch for use in ‘last meter’ (also sometimes ‘first meter’) body area networks.
