Body Sensor Network (or Body Area Network, BAN) design and implementations are growing for wireless health monitoring applications. NXP Semiconductor introduced a versatile ultra-low power biomedical signal processor, CoolBio™, meeting the requirements of future wearable biomedical sensor systems. Intelligent body area networks (BANs) consisting of wireless sensors nodes which continuously monitor vital body parameters such as heart, muscle and brain activity promise to be a solution for more comfortable, cost-effective and time-efficient healthcare systems. They allow people to be monitored and followed up at home, doing their daily life activities.

A major challenge in developing such Body Sensor Networks is to bring overall power consumption down to a level where the system can be powered by energy harvesting or a microbattery that runs for months. The CoolBio biomedical signal processor allows drastic power reduction of the wireless BAN biomedical sensor nodes. Processing and compressing data locally on the BAN node limits power hungry transmission of data over the wireless link, while adding motion artifact reduction and smart diagnosis at the same time.

NXP CoolBio biomedical signal processor consumes only 13pJ/cycle when running a complex ECG (electrocardiogram) algorithm at 1MHz and 0.4V operating voltage. This biomedical signal processor is programmable using C-language. CoolBio biomedical signal processor is voltage and performance scalable supporting a frequency range of 1MHz up to 100MHz with an operating voltage from 0.4 to 1.2V.

“Ultra low power dissipation is a critical requirement for ubiquitous deployment of Personal Health solutions. NXP continues to push the envelope on all critical functions required in wearable healthcare solutions. CoolBio complements our comprehensive ultra low power portfolio with which we enable solutions improving people’s quality of life;” said Bart De Loore, VP New Business at NXP.
