Abstract :
We studied the compatibility between a piezoelectric ceramic and a biological suspension: (i) the influence of this substrate on the cell population and (ii) the influence of the cell suspension on the piezoelectric ceramic. We used a 40 mm diameter/0.5 mm thickness niobium substituted PZT wafer. The wafer was put in a Petri dish containing a cell suspension, a second Petri dish containing the same biological medium without ceramic wafer beeing kept as reference. Both Petri dishes were observed for 4 days in order to see the cell population development. The ceramic surface was not affected nor the cells development.
