Hydrogel-based Sensors

Hydrogel-based sensors are advanced devices that use special water-absorbing materials called hydrogels to detect various substances, like chemicals or changes in temperature. These sensors work by interacting with their environment: when they come into contact with certain substances, their properties change, which can be measured. Because they are flexible and can hold a lot of water, hydrogels are particularly useful in applications like health monitoring, environmental sensing, and smart textiles. Their ability to respond quickly and accurately makes them valuable tools in science and technology.
