Toumaz Technology Ltd. (Abingdon, England), a developer of low-power wireless body monitors, has announced that its Sensium Life Pebble, a body-worn vital signs monitor, has been awarded a CE mark. This means it can now be sold and deployed in 27 countries in the European Union and all other countries that have adopted the CE standard for certified medical devices.
The Sensium Life Pebble TZ203002 is a tiny vital signs monitor that continuously monitors the user’s ECG, heart rate, physical activity (using a three-axis accelerometer) and skin temperature and streams the data over a short-range (around 5 m range) to a Sensium USB adapter or data logger. The Life Pebble is designed for use in a wide range of professional applications including sports monitoring, lifestyle, and health care.
The Sensium Life Pebble can be used on its own or fitted in a flexible holder and attached to the body around the torso, leg or arm with an elastic belt. Data can be continuously transmitted to a USB adapter plugged into a PC for real time capture and analysis, or sent to a small USB data logger for storage and subsequent download and analysis.
Data from multiple sensors can be transmitted continuously in raw form or be pre-processed in the Life Pebble to report only adverse or notable events, such as automatic detection of falls or cardiac arrhythmia. A version of the Life Pebble for use in professional sports applications is in the prototype phase.
The Life Pebble TZ2030 uses Toumaz Technology’s unique Sensium platform to enable continuous data capture, local processing, and wireless transmission at ultra low power. The device can operate up to five days on a single hearing aid battery and weighs 20 grams including an LR44 battery. Much of Toumaz's technology is based on operating CMOS transistors as analog devices at very low voltage in a non-linear sub-threshold region, with corresponding savings in power consumption.
