Radio Chip Designed for Medical and Sensor Applications

Tue, 05/26/2009 - 6:59am


Zarlink Semiconductor Inc. introduces a radio chip that delivers the unique combination of ultra-low peak power and very high efficiency to enable continuous monitoring in a broad range of medical and sensor applications. Customers are evaluating the ZL™70250 radio chip for use in on-body devices such as electrocardiograms (ECGs) that record heart activity, oximetry systems that measure oxygen levels in the blood (SpO2), continuous glucose monitors (CGM) for diabetes patients, and sound and voice communication systems. Consuming less than 2 milliwatts (mW) with an efficiency of 11 nanojoules per bit (nJ/bit) - fives times less power than competing devices - the ZL70250 radio chip allows designers to significantly shrink the size of existing wireless devices and extend operating life. In addition, the ultra-low power performance allows the device to be operated directly from coin cell batteries, enabling the design of very compact devices previously not possible due to battery size limitations.
