Graphene heart rate sensing system

The invention provides a graphene heart rate sensing system which is large in scaling range and high in sensitivity. The defects of a traditional heart rate sensor, particularly a traditional grapheneheart rate sensing system are overcome. The sensor has the advantages of being high in sensitivity, simple in manufacturing technology, large in production scale, low in cost and the like. The graphene heart rate sensor has excellent sensitivity and large working range and can have good linearity in the range of low pressure and high pressure. 本发明克服传统心率传感器特别是石墨烯心率传感系统的缺陷，提供了种量程范围大，灵敏度高的石墨烯心率传感系统。传感器具有灵活性高，制作工艺简单，生产规模大，成本低等优点。本文提出的石墨烯心率传感器具有出色的灵敏度和较大的工作范围，在较低压和较高压范围内都能有良好的线性度。
