Abstract

One of the main topical problems that biomedical discipline has the develop of medical equipment, prosthesis, diagnostically and therapy equipment, and the others. In the last field in which the work has been stimulated by the successful develop of methods for monitoring biological signal. Moreover, the aging of the humanity is the key that motivates more research in new instruments for diagnostic and therapy and the investment about new ways to have more information about the state of human health. The development of new instruments entails the research focuses on new sensors or the improvement of the already existing ones; in this background the called smart materials are the option of choice to develop sensors and instruments based on these materials due to its thermal, mechanical, optical and electrical responses that permits to detect a variety of physics constants and at the same time are characterized for strong structure, a wide range of work frequencies, wide range of temperature operation among others features. Several studies have been carry out in order to get the optimal material combinations such as the influence of compositionally modified ceramic bodies, or the addition of a variety of elements obtaining a doped ceramics, on the other hand multilayer capacitors, based on smart materials, are base of a variety of studies and are widespread use in the electronic market, having these concepts in mind, a metallic wire was inserted into a ferroelectric ceramic bulk, the wire has more than one propose in the ceramic: using this wire implanted, a free ceramic face is obtained and at the same time the implant provides a free charges that modify ceramic behavior, this face is used in order to measure optic and mechanic events, the wire in total immersion into the ceramic also serve as control electrode and it is named Ceramic controlled piezoelectric (CCP), (Gonzalez & Suaste, 2009).
