Bioelectrical impedance analysis applied to pneumographic investigation is a technique for monitoring the respiratory activity through the measurement of variations in the trans-thoracic electrical impedance. In this paper, a low-cost reconfigurable measurement system is presented. The system is based on a 4-electrode volt-amperometric technique and a network of inertial sensors for correction of arms motion artifacts. The trans-thoracic impedance was acquired via an ad-hoc programmed LabVIEW software.

Wearable technology is attracting most attention in healthcare for the acquisition of physiological signals. We propose a stand-alone wearable surface ElectroMyoGraphy (sEMG) system for monitoring the muscle activity in real time. With respect to other wearable sEMG devices, the proposed system includes circuits for detecting the muscle activation potentials and it embeds the complete real-time data processing, without using any external device. The system is optimized with respect to power consumption, with a measured battery life that allows for monitoring the activity during the day.
