The SensiumTM: Designing a Robust and Reliable Ultra-Low Power System-on-Chip for Wireless Medical Monitoring

Alison Burdett, Toumaz Technology


Medical devices need to achieve very high levels of reliability. Hardware redundancy and software self-test routines are typically employed to guarantee device operation, and extensive testing post-manufacture is needed. As a result, components designed for use in medical devices are significantly more expensive than similar components intended for use in consumer devices.

Toumaz Technology has recently developed the SensiumTM; an ultra-low power system-on-chip (SoC) for wireless medical monitoring. This SoC is integrated with appropriate sensors and printed battery to produce a disposable patch – or ‘digital plaster’ – which can be used to monitor the vital signs of a patient. Since the patch is disposable, low cost is important, but high levels of reliability are still necessary. This talk will discuss how self-test and reliability were inherently designed into the Sensium, to ensure the goals of robust operation and low manufacturing costs could both be achieved.
