“…Phase shift is therefore solely introduced by the input capacitance C in . This result is consistent with traditional design strategies which state that low-frequency distortion can be prevented if R in C in > 1/ω c , since other capacitive effects are neglected (Bergey et al, 1971;Valverde et al, 2004). As frequency increases, the effects of C 2s and C 4e must be considered and eq.…”

“…Since its dry contact, the high skin-electrode impedance must be characterized to interface with sensor readout circuitry. With the method reported in [16], the measurement was started after 5 minutes electrode attachment for stabilizing the contact. To maintain an equal contact during the measurement, a constant pressure of 20 mmHg is applied on electrode with the help of pressure cuff.…”

Abstract-This paper describes the development of a low-power electrocardiogram (ECG) touch sensor intended for the use with two dry metal electrodes. An equivalent ECG extraction circuit model encountered in a ground-free two-electrode configuration is investigated for an optimal sensor read-out circuit design criteria. From the equivalent circuit model, (1) maximum sensor resolution is derived based on the electrode's background thermal noise, which originates from high electrode-skin contact impedance, together with the input referred noise of instrumentation amplifier (IA), (2) 60 Hz electrostatic coupling from mains and motion artifact are also considered to determine minimum requirement of common mode rejection ratio (CMRR) and input impedance of IA. A dedicated ECG read-out front end incorporating chopping scheme is introduced to provide an input referred circuit noise of 1.3 V rms over 0.5 Hz ~ 200 Hz, CMRR of IA > 100 dB, sensor resolution of 7 bits, and dissipating only 36 W. Together with 8 bits synchronous successive approximation register (SAR) ADC, the sensor IC chip is implemented in 0.18 m CMOS technology and integrated on a 5 cm × 8 cm PCB with two copper patterned electrodes. With the help of proposed touch sensor, ECG signal containing QRS complex and P, T waves are successfully extracted by simply touching the electrodes with two thumbs.
