A review of the research progress of graphene pressure sensors in wearable electronic devices 3

The design of graphene pressure sensors is usually based on its resistance change principle. When under pressure, the contact area and thickness of graphene will change, resulting in a change in its resistance value. By measuring the change in this resistance, the magnitude of the applied pressure can be accurately detected.diode

There are various methods for preparing graphene pressure sensors, including chemical vapor deposition (CVD), mechanical exfoliation, liquid-phase exfoliation, etc. Among them, CVD method is widely used due to its ability to produce large-area and high-quality graphene.diode

Application prospects

1. Health monitoring

Graphene pressure sensors are particularly suitable for use in the field of health monitoring due to their excellent sensitivity and flexibility. They can be integrated into clothing or skin patches to monitor vital signs such as heart rate, breathing, and blood pressure in real-time.diode

2. Sports tracking

In sports science, graphene pressure sensors can provide accurate motion tracking data. For example, sensors integrated into sports shoes can help analyze gait, optimize athletic performance, and reduce the risk of injury.diode
