From the chair

The 2012 Symposium on Piezoelectricity, Acoustic Waves, and Device Applications(SPAWDA 2012) was held at Shanghai with the enthusiastic participations of engineers, professors, students, and business leaders all over China and preeminent researchers in this industry from China, Singapore and the United States. Once again, we had a great event with the ever increasing support from industry and academia through core groups working on materials, physical acoustics, product development, manufacturing, and applications of piezoelectric acoustic wave devices for frequency control and detection in China. The Symposium, as before, has been sponsored by the Chinese Society of Theoretical and Applied Mechanics(CSTAM), Acoustic Society of China(ASC), and the IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society(UFFC-S).
