TL;DR
This paper introduces a new ultrasonic device inspired by leaf-cutting ants that can operate over a wide frequency range and may be useful in medical and industrial applications.
Contribution
A novel biomimetic ultrasonic vibrator inspired by leaf-cutting ants is designed and tested for broadband performance.
Findings
The BUV operates in the frequency range of 16.8–19 kHz with stable vibrations and displacement amplitude over 22 µm.
The BUV has a broader operating frequency band compared to piezoelectric and magnetostrictive transducers.
The BUV can cut soft rubber and pig tissues, showing potential for use in high-power micro operations.
Abstract
Power ultrasound is widely used in industrial production, medical equipment, aerospace, and other fields. Currently, there are two main types of commonly used power generation devices: piezoelectric ultrasonic transducers and magnetostrictive ultrasonic transducers. However, in certain situations with limited external dimensions, the applications of existing power ultrasound devices are limited. In nature, leaf-cutting ants excite vibrations through their tiny organs. Inspired by the vibratory organs of leaf-cutting ants, a new type of biomimetic ultrasonic vibrator (BUV) comprising a scraper, dentate disc, and fixture system was proposed, fabricated, and tested in this study. The experimental results showed that the BUV could operate in the frequency range of 16.8–19 kHz. Within the working frequency range, the vibration of the BUV was stable and the amplitude of the vibration…
