Circuit device for controlling insect flight behavior based on electrical stimulation

Abstract

The invention discloses a circuit device for controlling an insect flight behavior based on electrical stimulation. The device is composed of three parts including an upper computer, a coordinator andan electronic backpack, wherein the upper computer is connected with the coordinator through a serial port, and the coordinator is connected with the electronic backpack in a wireless communication mode. The upper computer is implemented based on a Labview platform and sends a flight instruction to a lower computer through a serial port; the coordinator part mainly comprises a USB / serial port circuit, a first microprocessor and a ceramic antenna, and realizes connection between a wired network and a wireless network; and the electronic backpack is composed of an electric stimulator, a secondmicroprocessor, a ceramic antenna, an analog MEMS microphone, a nine-axis sensor and a micro battery, is small in size and light in weight, can be carried on the body of a beetle and is an executive device of the whole circuit. According to the circuit device, stimulation signal parameters can be changed in real time and insect flight information acquired by the lower computer is displayed at thesame time, and the design requirements of low cost, high reliability, low power consumption, multifunctionality and the like are met.

Description

technical field [0001] The invention relates to related fields such as microelectromechanical systems (MEMS), wireless communication technology and biology, and in particular to a circuit device for controlling insect flight behavior based on electrical stimulation. Background technique [0002] Insects are the most numerous organisms on earth. Their size ranges from less than 1 millimeter to more than 20 centimeters, and they have amazing mobility and can quickly traverse complex terrain. Because of their small size and powerful functions, they have attracted researchers to study insect biomimetic robots, but even Even the most advanced bionic robots are far inferior to the insect's own motion system in terms of power efficiency and motion controllability, because on the one hand, we lack sufficient understanding of insect motion systems, and on the other hand, existing control technologies are limited. However, it is difficult to realize the precise mechanical structure a...
