Temperature evaluation of soft and hard PZT transducers for ultrasonic

Johansson, Linda ; Evander, Mikael LU ; Lilliehorn, Tobias ; Almqvist, Monica LU ; Nilsson, Johan LU ; Laurell, Thomas LU and Johansson, Stefan (2005) Micro Total Analysis Systems 2005 2. p.1428-1430
Abstract
This paper reports a comparison of soft and hard piezoceramic transducer materials used for ultrasonic particle trapping in a microfluidic bioanalytical platform. The investigation is made with the objective to obtain high acoustic forces with a minimum of temperature increase. Themperature is a critical parameter for bioassays and most often need to be kept below a certain level to allow handling of e.g. temperature sensitive proteins. The main conclusion in this paper is that it is possible to get efficieint trapping with a temperature increase of only a few degrees using a hard type III transducer material.
