Acoustic Levitator : 27 Steps (with Pictures) - Instructables
Acoustic Levitator: Use acoustic waves to hold in mid-air samples such as water, ants or tiny electric components. This technology has been previously restricted to a couple of research labs but now you can make it at your home.
Acoustic levitation - Wikipedia
Acoustic levitation is a method for suspending matter in air against gravity using acoustic radiation pressure from high intensity sound waves. [1] [2] It works on the same principles as acoustic tweezers by harnessing acoustic radiation forces. However acoustic tweezers are generally small scale devices which operate in a fluid medium and are ...
How Acoustic Levitation Works - HowStuffWorks
Aug 23, 2023 · A basic acoustic levitator has two main parts — a transducer, which is a vibrating surface that makes sound, and a reflector. Often, the transducer and reflector have concave surfaces to help focus the sound. A sound wave travels away …

Customized and high-performing acoustic levitators for contact …
Sep 1, 2024 · Acoustic levitator Mk3 is unique due to the close packing of transducers in a hexagonal arrangement, which led to the highest stability and levitation strength among all designs. These characteristics are important in applications related to spectroscopical techniques where high-level control of the levitated samples displacement is crucial.
声悬浮器 - COMSOL 中国
超声驻波悬浮器也称为声悬浮器，是一种使流体和固体颗粒在声场中悬浮的装置。驻声波对颗粒施加声辐射力，此辐射力源于粒子和声场之间的时均压力和惯性相互作用的共同作用，通过使颗粒悬浮，可以研究颗粒在不同温度和湿度等外部条件下的干燥动力学特性等。
MightyLev: An acoustic levitator for high-temperature …
Oct 9, 2024 · “MightyLev” is a new multi-emitter ultrasonic acoustic levitator capable of extremely stable levitation of medium- to high-density materials up to at least 11.3 g cm −3. The extremely small (micro-scale) displacements observed during levitation make the device ideally suited for integration with micro-focused optical spectroscopy or x-ray ...
TinyLev: A multi-emitter single-axis acoustic levitator
Aug 10, 2017 · Here, we design, build, and evaluate a single-axis levitator based on multiple, low-voltage (ca. 20 V), well-matched, and commercially available ultrasonic transducers. The levitator operates at 40 kHz in air and can trap objects above 2.2 g/cm 3 density and 4 mm in diameter whilst consuming 10 W of input power.
The Acoustic Levitator - Instructables
The Acoustic Levitator is a really fun project for young scientists and engineers alike. It uses high-frequency sound waves to create intense pressure areas in the air. If you are interested to learn how it works click here. This project uses a total of 72 transducers to levitate objects such as water droplets and polystyrene balls(1-3mm diameter).
Acoustic levitation with optimized reflective metamaterials
Mar 6, 2020 · We apply our method to demonstrate a new type of acoustic levitator, based on a simple single-phased array of transducers and a reflective acoustic metamaterial, capable of levitating objects...
