摘 要：In recent years, interest towards wearable sensors and medical monitoring has exploded. Despite e orts to improve health care with medical technology, many people still die today from the lack of proper health management. Bio-sensors can provide long-term, continuous monitoring of key bio-signals and enable proactive personal health management [1]. Since the bio-sensors are worn in some manner, ultra-low power consumption is critical. Conventional sensors use Nyquist sampling to capture key information in bio-signals; hence, the operation is very costly. Compressed sensing exploits data redundancy arising from a low rate of signi cant events in a sparse signal. The data is compressed at the sensor node and therefore, the power required to transmit the compressed information to a receiver (e.g., smartphone) is minimized. The compression factor of a sparse bio-signal can be much larger than one, thus providing signi cant power eciency in wireless sensors.
