Ultra-low-power radio technology is enabling wireless wearable technology featuring long battery life and small form factor for medical and other fields.
In today’s wearable technology, long battery life and small form factor are critical design requirements for wireless sensing and monitoring devices. Radio transceivers embedded within these wearable devices need to support continuous data streaming with extremely low power consumption. This is especially critical for wearable platforms systems that are used in environments where frequent battery replacement would be difficult and impractical. Although systems previously required AA or AAA batteries, many can now operate using +3V coin cell batteries. Making this possible are ultra-low-power short-range radio transceivers whose circuit design has been optimized for power efficiency across several key parameters. With improved ultra-low-power consumption, which allows the use of tiny coin cell batteries, wearable applications can be further reduced in size with the use of radios available in a smaller chip-scale package (CSP).
