Controlling and modifying at will the transparency, electrical properties, and stiffness of a gel are among the promises of new research by scientists supported by the Swiss National Science Foundation (SNSF). Their discovery marks an important step for materials used in healthcare, high-tech, and the cosmetics industry. Gels can be found everywhere: from contact lenses to ink, from sensors to medical electrodes and even breast implants. Their ultra-absorbent properties, flexibility, and grip make them appealing to researchers and manufacturers. They consist of a network of solids that can retain up to 99% of liquid while maintaining their shape. EPFL researchers have just published how to combine two gels in such a way that they can monitor and change, almost at will, the properties of the new combined material.
