Abstract

The invention belongs to the technical field of biomimetics and discloses a flexible electromagnetic elastomer device with the simulation of a chameleon tongue and a manufacturing method thereof. Thedevice comprises an electromagnetic coil, a sleeve, a blocking structure, a soft tongue and a metal block, wherein the inside of the sleeve is a cylindrical first hollow structure, the outer portion of the sleeve is provided with the electromagnetic coil according to the magnitude of ejection force, the blocking structure is disposed at one end of the first hollow structure, and the soft tongue includes an ejection member and an extending member. The invention also discloses a manufacturing method of the corresponding device. The device can simulate the ejection process of the chameleon tonguewell and has the advantages of compact structure, small energy consumption, fast ejection speed and automatic recovery, the electromagnetic coupling / interaction characteristics of a flexible electromagnetic material are used, the ejection of the chameleon tongue to drive a whole body can be achieved with only an instantaneous discharge process, the required voltage and energy consumption are reduced, and at the same time, the mechanical energy conversion efficiency is high.

Description

technical field [0001] The invention belongs to the field of bionics, and more specifically relates to a flexible electromagnetic elastic body device imitating a chameleon tongue and a manufacturing method thereof. Background technique [0002] Bionics is an interdisciplinary subject combining engineering technology and biological science developed in recent years. It is a subject developed in the process of human imitating nature. Through the research and improvement of some structures about plants and animals, it has surpassed the technical design scheme of human beings in this respect. During millions of years of natural evolution, plants and animals not only fully adapt to nature but also approach perfection. Biomimicry attempts to imitate the functions of animals and plants in nature in terms of technology, and this technology is called bionic technology. At present, the utilization methods of biomass at home and abroad mainly include combustion, pyrolysis and gasific...
