dc.description.abstractClassical approaches to make high-quality ECG measurements require the use of shielded cables connecting gel electrodes to a central unit. Moreover, impedance measurement requires at least two additional electrodes for current injection. CSEM has developed a concept based on dry-electrode sensors able to simultaneously measure ECG and thoracic impedance. Prototypes with discrete components were built to validate the correctness of CSEM approach [1]. Following this, an ASIC was realized in order to drastically reduce the system size. The small system size (56×25×5.5mm) and the simplicity of the cabling (only one unshielded and possibly uninsulated wire) make the system highly wearable and easy to integrate in a garment, thus improving the patient comfort. A demonstrator was realized in order to assess the ASIC performances in real life scenario. This paper presents the results of this development.
