Low-power wireless medical sensor platform.
Long-term, low duty cycle monitoring of patients with a variety of disabilities or health concerns is often required. In this paper, we discuss the design considerations and implementation of an ultra-low power wireless medical sensor platform, suitable for a wide range of medical and sports applications. A hardware demonstration prototype based on readily available components is presented with sensors for 3-axis acceleration, temperature and galvanic skin response. Detailed power measurements and operation results are shown, demonstrating a sensor life span of more than 10 years on a single 200 mAh lithium watch battery using low current standby techniques with an average power of less than 5 muW and a 10 second sample interval.
