DEVICE FOR THE DETECTION OF BIOELECTRIC POTENTIALS WITH CERAMIC PIEZOELECTRODES WITH PLATINUM IMPLANT.

Abstract

A device for detecting bioelectrical and / or biophysical potentials is described, for measuring electrophysiological signals individually or simultaneously, such as: electrocardiogram (ECG), electromyogram (EMG), electroencephalogram (EEG), electroocuiogram (ECG), electroretinogram (ERG), electrogastogram (EGG), and optionally the simultaneous measurement of heart rate, body temperature, skin moisture, heart sounds, and / or respiratory rate. The device is characterized in that it comprises: (i) at least one first electrophysiological signal sensor (21) of controlled piezoelectric ceramic (CPC), having a surface contact face, a lower terminal, and a platinum wire insert; (ii) at least one second electrophysiological signal sensor (22) of controlled piezoelectric ceramic (CPC), having a surface contact face, a lower terminal, and a platinum wire insert;(iii) a reference electrode (23) having a surface contact face, and a terminal connecting to the common input of the electrically isolated amplifier; (iv) an electrically isolated amplifier (30), having a negative terminal connected to the lower terminal (14) of said at least one first controlled piezoelectric ceramic (CPC) sensor (23), a positive terminal connected to the lower terminal of said at least one second controlled piezoelectric ceramic (CPC) sensor (24), and a common terminal, connected to said reference electrode, to the platinum wire insert of said at least one first controlled piezoelectric ceramic (CPC) sensor, and to the platinum wire insert of said at least one second controlled piezoelectric ceramic (CPC) sensor; (v) a second amplifier with synchronous demodulation, connected to the output of the electrically isolated amplifier;and (vi) a physiomonitor that displays a waveform, in turn connected to the amplifier with synchronous demodulation.;
