Scientists Developed Recyclable Self-Healing e-Skin that Can Sense Pressure and Temperature
Scientists Developed Recyclable Self-Healing e-Skin that Can Sense Pressure and Temperature, Scientists have just taken another step in the field of biomedicine by developing an eco-friendly electronic skin that can be completely recycled. The e-skin is a thin, malleable, self-healing, and fully recyclable that can act like your skin through measuring temperature, pressure, humidity, and air flow. China and US-based researchers have made electronic devices more-friendly and have applications ranging from robotics, prosthetic development, and smart textiles to revolutionize biomedical devices.
The e-skin also called electronic skin is basically a semi-transparent thin film equipped with sensors can mimic the function and mechanical properties of human skin through its embedded sensors that can measure pressure, humidity, temperature, and airflow, according to a report published in the journal Science Advances.
The electronic skin is made from a mixture of polymer network called polyimine and silver nanoparticles that provide better mechanical strength, chemical stability, and electrical conductivity. When the device is cut in two can heal itself by recreating chemical bonds between the two sides. “What is unique here is that the e-skin can recycle itself by soaking in a solution that liquefies it and can heal itself by mixing compounds found in ethanol with the material at room temperature,” said Jianliang Xiao, an assistant professor from the University of Colorado Boulder. Another added bonus of the new e-skin is that it can be easily applied to curved surfaces like human arms and won’t produce any waste that needs to be disposed of.
The e-skin will prove a boon for the robots also. In the future, when robots could be handling babies in some form, they would be able to feel for pressure and temperature. This will ensure safe handling of a baby by a robot and will help in detecting a fever also. The idea is to mimic the biological function through its embedded sensors. Today, many labs around the world are demonstrating e-skin including Europe and Japan.
