Cardiac skin micropulsation acquisition system based on pressure sensor made of PLZT with implant

From the development of a disc of ceramics made with lead lanthanum zirconate (PLZT) and implanted with platinum wire, important applications became. In this case already the successful functionality of the detection of the cardiac pulse with this ceramics has been reported; nevertheless the present work shows the development of this sensor with a system of data acquisition that is very important for the signal records, analysis and comparison of cardiac pulses and electrical registry of the heart. The system of acquisition of pulse shows in a computer screen a friendly atmosphere to us that can be adapted to diverse situations of measurement.
