LONDON Toumaz Technology, a developer of RF, analog and mixed signal semiconductors targeting medical electronics applications, has successfully tested its integrated Sensium platform in a device aimed at health and lifestyle monitoring.
The company says the chip, which taped-out on Infineon's 130-nm RF CMOS process in November 2006 less than 18 months after initial specification, has met all targeted accuracy and performance parameters in initial functional testing.
Toumaz (Abingdon, England) announced last October the availability of a wearable, multi-function Sensium system in modular form. Now, the company says, with the delivery of the integrated platform incorporating the ultra-low power wireless transceiver (including both RF and baseband functionality), reconfigurable sensor interface and digital block with a low power 8051 processor and memory on a single 4 x 4 mm chip it has reached a "key milestone on the road to volume production of Sensium-enabled health and lifestyle monitoring devices."
The systems will be made available to Toumaz's healthcare and pharmaceutical customers for trials from the beginning of March.
The ultra-low power wireless platform will allow healthcare providers to remotely monitor vital signs and other bio-markers from mobile individuals in real-time, via PDAs, mobile phones, and USB-enabled computers, says Toumaz. The company adds this first version of the Sensium is the precursor of a range of ultra-low power sensor interface systems currently being readied for healthcare markets.
"Toumaz has succeeded in pulling together the key core competences of ultra-low power wireless and ultra-low power signal processing first developed at Imperial College and integrating these on to a system for the acquisition of data from a mobile individual," commented Toumaz Technology co-founder and Chairman, Professor Chris Toumazou.
The company claims the Sensium platform represents advances in three areas: Gathering real-time information, not raw data; ultra low power; and as an end-to end system.
It uses on-chip signal processing to extract critical information from sensors, providing real-time feedback to patients; the patented AMx technology coupled with low power radio and intelligent information handling results in an ultra-low power, body-worn solution, enabling non-intrusive, continuous monitoring; and the platform offers low power radio link from the patient to the communications network and into the healthcare provider's database/system.
