An attempt has been made to provide the ranking of piezoelectric and pyroelectric materials using technique for order preference by similarity to ideal solution ( TOPSIS ) method. To calculate weight (priority) for all the attributes (properties) understudy, entropy method is used. Interestingly my results suggest that dielectric constant is a key parameter (after d 33 coefficient) which governs selection of piezoelectric materials. PLZT (8/65/35) and LiTaO 3 ceramics place on first rank among studied piezoelectric and pyroelectric materials, respectively. These materials are classified using hierarchical clustering which shows similarities between the materials irrespective to their ranking obtained using TOPSIS method.
