The Engineer Online profiles Toumaz Technology, a spin-off from Imperial College London, that has developed the Sensium™, a chip featuring technology that consumes up to 100 times less power than any other chip designed for a wireless body monitoring network.
Coupled with external sensors such as heart rate monitors or biochemical sensors that monitor glucose or blood pH levels, it is hoped that the chip could be used to continuously monitor patient health.
Toumaz director of technology Dr Alison Burdett believes that wireless body networks – where patients can be remotely monitored 24 hours a day – is only possible if the battery that powers the sensors is not cumbersome or intrusive.
‘Its low-power consumption is key. It will open up a range of applications where small size is important, particularly for body-worn and healthcare applications,’ she said.
