Abstract

Piezoelectric ceramics were made by a doctor blade methode and piezoelectric fans were fabricated by sandwiched a slim and long metal between two layers of ceramics. A maximum displacement of piezoelectric fan occurs in the resonance frequency of a long metal and the resonance frequency of them is in inverse proportion to the square of a length of metal. The piezoelectric fan made from a wide and thin piezoelectric ceramics($13{\times}0.2{\times}30mm^3$) showed a maximum displacement in all samples, and the maximum displacement was about 20mm in a commercial power (200V, 60Hz of sine wave).
