Body heat-powered heart beat detection circuit
Technology Description The inventors have designed, implemented, and demonstrated an integrated circuit architecture for robust and automated detection of heartbeats from a two-electrode ECG signal. This uses sufficiently low power (~20μW) that it can be powered entirely by human body heat from a cm-scale TEG module at ~20mV, including wireless...
