Abstract
The main objective of this project is to study and develop macroscopic devices for the noncontact levitation and manipulation of particles in air. Noncontact manipulation of particles by ultrasonic standing waves has many potential applications in the areas of biotechnology, analytical chemistry and in microelectronics. Due to the acoustic radiation force, it is possible to suspend and manipulate particles in liquids and in gases. The manipulation of particles can be achieved by the spatiotemporal modulation of the standing wave field, which allows controlling the position of the particle immersed in a fluid. The development of noncontact manipulation devices will be performed by using computational simulations with the Finite Element Method, which will be used in the design and optimization of the noncontact manipulation devices. After performing the simulations, the manipulation devices for the acoustic levitation and manipulation of particles will be fabricated and characterized. The devices for manipulation in air will be formed by ultrasonic transducer with a resonance frequency between 20 and 40 kHz. (AU)
