▎ 摘　　要

NOVELTY - The meter has a first contact electrode (1) and a second contact electrode (2) that supports a graphene strip (7) to form a suspended graphene mechanical vibrator. The first contact electrode and the second contact electrode are used as source and drain electrodes to input and output drive and detection signals. The height of the first contact electrode and the second contact electrode is greater than that of a gate electrode (3). Different voltage biases are applied to the gate electrode. An adjustable electrostatic field is applied to the graphene vibrator to adjust the sensitivity and response speed of the bolometer. The described bolometer monitors the resonant frequency of graphene machinery in real time by electrical or optical methods, and realizes the sensing of radiation intensity by measuring the frequency shift response of the graphene mechanical oscillator under light radiation. USE - Adjustable radiation heat meter based on graphene of mechanical vibrator. ADVANTAGE - The simple structure, strong robustness, fully exerts the high sensitivity and high response rate of the high frequency graphene the suspended characteristics, and the graphene nano electromechanical system electrically flexible and adjustable are ensured by performance adjustable radiation pyrometer, so as to keep stable performance for a long time inside and is measure to the requirement of various temperature environments from normal temperature to low temperature environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of the performance-tunable bolometer based on the graphene mechanical vibrator. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of the adjustable radiation heat meter based on graphene of mechanical vibrator.
