John materials

John materials are a class of advanced materials characterized by their ability to change properties, such as shape or stiffness, in response to external stimuli like temperature, stress, or electric fields. They are often used in applications requiring adaptability, such as soft robotics, medical devices, and aerospace. These materials can "remember" or respond to specific conditions, enabling innovations in design and functionality. Their unique responsiveness combines the flexibility of traditional materials with smart, dynamic behavior, making them valuable in developing more versatile and efficient technologies.
