Abstract

Since graphene wearable strain sensor in the monitoring of human life characteristics shows great application prospects, using porous cube sugar (C12H22O11) as sacrificial layer by us, the composite structure of graphene and dimethylsiloxane was prepared by a new method, and then achieve pressure sensing and photoelectric conversion performance. Utilizing porous sugar cubes as an alternative to conventional Cr templates not only reduces expenses, but also offers exceptional water solubility and environmental friendliness. Moreover, this sensor exhibits the capability to detect micro-scale vibrations within the human body, enabling precise monitoring of pulse and carotid artery movements, holding significant potential for diverse applications.
