Abstract

Electrical properties of hydroxyapatite (HA) in the form of screenprinted thick films that can be used as a biocompatible coating for bone and dental implants are reported. In particular, piezo and pyroelectric behaviour of these films suggest that they can be used to promote faster healing of bones and prevent rejection of implants. Moreover, the reversible pressure-induced changes in their electrical characteristics can be employed for real-time in vivo pressure sensors implantable simultaneously, for example, with knee or hip prosthesis. The additional advantage of HA in the form of screen-printed thick films is that, due to the technology's versatility, it can be produced on flexible substrate in any shape and size to suit the needs of various patients.
