Design of a low-power, low-cost ECG & EMG sensor for wearable biometric and medical application

With the advent of IoT and growing health awareness, the applications of wearable ECG & EMG sensors have grown manifold. These applications demand the sensors to be low-cost, low-power and highly portable. These requirements put several limitations on the wearable ECG & EMG sensors design and development. This paper presents a new ECG & EMG sensor which had power consumption less than 1.65 mW (I<;500 pA @ 3.3 V) and cost less than USD 10. The paper also discusses the implementation details and various testing results.
