- The use of wearable devices to monitor vital signs has become something usual, at the same time, here are an increasing demand in improving signal accuracy with a low power consumption. This work presents a conditioning circuit for electrocardiogram and surface electromyogram signals in a reliable way alongside filter and gain modules developed on the area of interest of such signals. At the end, the results obtained are presented, showing the conditioning capability of the circuit, leaving the proof of behaviour in real-life situations to be proven.
