Quantum materials are one the most important building blocks of smart devices of the future. What makes these materials interesting is that their magnetic and electronic properties can be controlled dynamically, leading to the development of crucial components such as memories. However, there is a limitation of quantum materials that once a device is  designed and produced, its mechanical characteristics cannot be changed. But researchers have discovered a method to stretch and compress quantum materials using hydrogen gas. The research will help in the development of products like inkjet printers, as sensors for environmental conditions and  future nano-electronics.
