METHOD AND APPARATUS FOR MEASURING BODY IMPEDANCE BASED ON BASEBAND SIGNAL DETECTION
摘要
Certain aspects of the present disclosure relate to techniques for measuring body impedance based on baseband signal detection in analog domain. Proposed methods and apparatus are able to measure an impedance of human body based on sub-Nyquist sampling of signals. The proposed techniques can be particularly beneficial for reducing overall sensor power when an actuation signal generates electrical signals corresponding to vital signs in humans.
