Problems solved by technology

[0003] However, there are still many limitations in the "wind speed detector" currently on the market, for example: its structure requires complex hardware circuit structures and software programs; At the same time, "wind speed detectors" such as propeller-type wind speed sensors, three-cup wind speed sensors and ultrasonic wind speed sensors that are common in the market are not yet mature, and have low sensitivity, poor accuracy, and dynamic performance. General and other shortcomings

Embodiment Construction

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The experimental methods for which specific conditions are not indicated in the examples are usually in accordance with conventional conditions or in accordance with the conditions suggested by the manufacturer.

[0027] The preparation steps of the wind speed tester based on graphene materials are as follows:

[0028] Step 1: Preparation of graphene film and PDMS bilayer structure

[0029] First, the substrate copper foil was placed in acetone, 95 vol% ethanol, and pure water for ultrasonic cleaning for 2 min each, dried with nitrogen, and then placed in the vacuum chamber of a tubular CVD system to prepare graphene to obtain a graphene film. like figure 1 As shown, 1 is a CVD tube furnace, 2 is a gas reaction chamber, 3 is a graphene material, 4 is a growth substrate, and 5 is a mechanical pump. A layer of PDMS with a thickness of 50um w...

Abstract

The invention discloses a wind speed tester based on graphene material. The wind speed tester comprises a graphene film and polymer double-layer structure and 3D conformal graphene. An electrode is disposed on the graphene film surface of the double-layer structure. Another electrode is disposed on the 3D conformal graphene. The double-layer structure and the 3D conformal graphene are superposed by using the polymer as a contact surface. The electrodes are connected via a wire. The wire is connected with a power supply and an instrument. The invention further discloses a manufacture method of the wind speed tester. The wind speed tester may satisfy all daily wind speed tests, may reflect a wind speed change in real time, is high in sensitivity and stability, good in biological compatibility, light in weight, simple in structure, and convenient to process, and can be directly manufactured by graphene material.

Description

technical field [0001] The invention belongs to the field of sensors, in particular to a graphene material-based wind speed tester and a preparation method thereof. Background technique [0002] "Wind speed tester" refers to a sensor device that can sense the wind pressure and convert the wind pressure into a usable output signal. The "wind speed detector" is mainly composed of "high performance wind speed sensor" and "microcomputer detection controller for the whole machine", so it can monitor and display the changes of the measured wind speed at the same time. The "wind speed detector" has broad application prospects. In the market, it has been used in fields such as meteorology, road and bridge, building, environmental monitoring, navigation measurement and new energy that need wind speed detection. The wind speed is digitally displayed by LED. The measurement range of the wind speed of the conventional "wind speed detector" is 0-30m / s, and the upper and lower limit valu...
