Abstract Scope |
Near-filed acoustic levitation (NFAL) has been a promising transfer printing method as attractive force is generated when the object is in small feature size relative to acoustic wavelength. The contact-free pick and place NFAL process is a promising concept to potentially be applied for micro manipulation such as the transfer printing of micro-light emitting diode (μLED). However, current NFAL research is limited at meter/millimeter scale, and it is not clear whether it is applicable at micro/nano level and whether the existing macroscopic prediction models still hold. This work establishes computational models to study the acoustic levitation effects at microscale with the goal of establishing a foundation for its potential applications in transfer printing of μLEDs. |
