Inspired by the snail’s ability to stretch the skin when swallowing very large prey, researchers at the US Terrasaki Institute have designed a sensor with high flexibility that can be used in a wide range of products related to medical engineering and cardiovascular health monitoring, athlete performance and rehabilitation. has it.
Many of the natural functions of the human body are associated with stretching and vibration on the surface of the skin. Many devices can monitor body activity by measuring such vibrations, but there is always a need for a more accurate and flexible sensor to build advanced devices.
Today’s sensors used in wearable technologies can detect tension from joints and muscles to very small vibrations from blood passing through arteries or vocal cords. PEDOT material: PSS is found in most of these sensors due to its very high conductivity and stability, which can be very sensitive in detecting the smallest stretches. Unfortunately, this material has very little flexibility, and previous attempts to add flexible materials to its composition have resulted in reduced sensitivity.
A joint team of researchers from the Trasaki Institute in the United States has for some time focused on increasing the flexibility of biosensors made from PEDOT: PSS. They are in Your research They are inspired by the snake skin’s ability to stretch many times when swallowing very large prey. The overlap of snake scales in the natural state allows them to be very far from each other when needed, giving the animal a very high degree of flexibility.
The researchers first placed a thin layer of the material on an elastic and flexible surface, and then considered the island-like structure of the polymer as the second layer. The result is a sensor with a very high flexibility without losing sensitivity.
A sensor made by the Terrasaki Institute can accurately detect the amount and angle of tension. Also, its resistance and sensitivity are at a very high level. Such findings have the potential to be used in a wide range of products related to medical engineering and cardiovascular health monitoring, athlete performance appraisal, and rehabilitation. It may even be used in new areas such as improving communication skills and recognizing utterances in crowded environments by tracking the movement of vocal cords or constantly monitoring facial movements to detect behavioral disorders.
