Abstract: The progress of sensors in biomedical applications is a huge driving force. In this study, through the synthesis process based on powder technology, a new PLZT (lead lanthanum zirconate titanate) sensor injected with platinum wire in longitudinal section was developed. Raw materials such as lead (PBO), lanthanum (La2O3), zircon (ZrO2) and titanium (TiO2) are used to form chemical components (62.8 PbO, 4.5 La2O3, 24.2 ZrO2 and 8.5 TiO2). Then, these powders are mixed and mechanically ground at high energy; Cylindrical samples with platinum wire implants were obtained by loading. Finally, the compacted sample was sintered at 1200 ° C for 2 hours, and then the polarization potential was 1500   V mm at 60 ° C to obtain Novl sensor. The density and porosity were evaluated using the Archimedes’ principle, while the mechanical properties such as fracture toughness value and Young’s modulus were determined by indentation and ultrasonic methods, respectively. A microscopic examination was also carried out to investigate the structural properties of the material. The PLZT novel sensor is electronically arranged for monitoring the cardiac pulses through a data acquisition system. The results obtained in this research are analyzed and discussed.
