Abstract
A low power highly sensitive Thoracic Impedance
Variance (TIV) and Electrocardiogram (ECG) monitoring SoC is
designed and implemented into a poultice-like plaster sensor for
wearable cardiac monitoring. 0.1
/10TIV detection is possible with
a sensitivity of 3.17 V
/10and SNR
40 dB. This is achieved with
the help of a high quality ( /81/45factor
30) balanced sinusoidal
current source and low noise reconfigurable readout electronics.
A cm-range 13.56 MHz fabric inductor coupling is adopted to
