Ultrasonic Standing Wave Suspension could the transducer support itself?

In summary, the conversation discussed the possibility of using an Ultrasonic Standing Wave Suspension to suspend a transducer from a reflector. The idea was inspired by the statement that a surface area of 1m2 could support 11.5kn at 16 Watts. The question was whether the same theory could be applied for suspending the transducer, even if the suspension point is at the second wave from the transducer. However, the reference provided suggests that the actual power required for such a suspension would be closer to 5kW, rather than the 16 Watts mentioned.

Ultrasonic Standing Wave Suspension could the transducer support itself?

Essentially looking at items that state a surface area of 1m2 could support 11.5kn at 16 Watts (Hemsel, 2013) could the transducer suspend itself from the reflector using the same theory even though the suspension point is at the second wave from the transducer if it were within the parameters of weight to surface area?

I fear you overlooked something.
They state clearly : "The first system was able to lift a weight of 3 kg using an electrical input power of only 16 W. Based on the surface area, a lift capacity of 11.5 kN/m2 was reached."
11500/30 ~ 380; 16W* 380 ~ 6000W, so even assuming peripheral losses will diminish when you scale up, 5kW seems to be a more reasonable estimate of the power required to lift 1.15 (metric) tons, given the technology used.
 

1. How does Ultrasonic Standing Wave Suspension work?

Ultrasonic Standing Wave Suspension is a technology that uses ultrasonic waves to create a standing wave pattern in a liquid or gas medium. This pattern creates nodes and antinodes, which can be used to suspend objects in mid-air. The transducer emits ultrasonic waves at a specific frequency and amplitude, creating a stable standing wave that can hold objects in place.

2. What is a transducer and how does it support itself in Ultrasonic Standing Wave Suspension?

A transducer is a device that converts one form of energy into another. In Ultrasonic Standing Wave Suspension, the transducer converts electrical energy into ultrasonic waves. The transducer is usually mounted on a stable base and is designed to support its own weight while emitting ultrasonic waves.

3. Can the transducer support objects of any size in Ultrasonic Standing Wave Suspension?

The size and weight of objects that can be suspended using Ultrasonic Standing Wave Suspension depend on the strength and stability of the standing wave pattern. Generally, the transducer can support small and lightweight objects, but may struggle with larger or heavier objects. The frequency and amplitude of the ultrasonic waves can also affect the transducer's ability to support objects.

4. Are there any limitations to Ultrasonic Standing Wave Suspension?

Ultrasonic Standing Wave Suspension has some limitations, such as the size and weight of objects that can be suspended and the stability of the standing wave pattern. It also requires a liquid or gas medium to work, so it may not be suitable for all environments. Additionally, the cost of the equipment and the complexity of the technology may limit its use in certain applications.

5. Is Ultrasonic Standing Wave Suspension safe?

Ultrasonic Standing Wave Suspension is generally considered safe as long as the appropriate precautions are taken. The ultrasonic waves emitted by the transducer are at a frequency that is not harmful to humans. However, it is important to follow manufacturer instructions and safety guidelines when using this technology to avoid any potential hazards.
