Abstract

The device described here is able to trap particles along the length of a channel, with distances between particle clumps larger than half an acoustic wavelength. It is actuated using a piezoelectric transducer adhered to a capillary, where the capillary defines the channel. A significant feature is that particles are located away from the opaque transducer and hence retain the ability to be viewed easily. Finite element modelling is used in order to explain the observed behaviour.
