Sustaining Continuous Monitoring Using Low-Cost Batteries

Today’s sensor and monitoring solutions for wireless personal area networks (WPANs) and wireless body area networks (WBANs) can support continuous data streaming with extremely low power consumption. This is critical for wearable medical systems that are used in environments where frequent battery replacement would be difficult and expensive. Now, systems that once required AA or AAA batteries can operate using 3 V coin cell batteries. Making this possible are ultra-low-power medium-range radio transceivers, whose circuit design has been optimized for power efficiency across several key parameters. The Figure below is a simplified RF circuit design with embedded loop antenna using chip-scale package (CSP).
