A “delicate machine,” the human body is packed with sensors like the fingers, nose, and mouth. Additionally, a large number of physiological signals are generated every second that can reveal the state of the body. Both the amount and the quality of physiological signals are crucial for making diagnosis and carrying out treatments.
The signals produced by commercial rigid sensors do not adhere well to the body due to the incompact interface between the sensors and the skin, which lowers the signal’s quality. It’s crucial to identify physiological signals in real time while going about daily life in order to increase the amount of data.
Wearable systems have clearly shown a tendency toward using graphene devices in recent years due to its exceptional performance (flexibility, biocompatibility, and electrical characteristics).
The quality and quantity of physiological signals can be enhanced using wearable graphene sensors, which has enormous potential for telemedicine and the future of healthcare.
The Global wearable graphene sensor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The LIG wearable graphene sensors provide a great range for strain measurements, going up to 10%. By printing the same electrodes on both sides of the film and using different measurements, a double-sided electrode concept was created.
This offered temperature correction together with a sizable bidirectional bending response. The ability to detect a wide variety of flow speeds, forces, and deflections is made possible by versatile design and an easy construction procedure.
The geometrical characteristics of the bending sensors and the LIG electrodes make it simple to adjust the sensor response. LIG bending sensors were employed as a wearable device to monitor body motion.
PDMS-coated LIG bending sensors were combined with ultra-low power aquatic tags for underwater operation and used in applications for underwater animal speed monitoring and a recording of the surface current velocity on a coral reef in the Red Sea.
