Description

technical field [0001] The invention relates to a multi-physical quantity detection sensor and a strain sensor based on graphene. Background technique [0002] Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. [0003] At present, there are many types of thin film sensors developed based on graphene, such as graphene temperature sensor film, graphene humidity sensor film, graphene strain sensor film, graphene pressure sensor film and so on. However, these existing sensors are generally sensors with a single function. When multiple sensors need to be used, the arrangement of each sensor becomes a difficult problem, and how to maximize the use of space becomes a problem to be solved. At present, the main research direction is still the preparation method of graphene se...
