Unlike traditional materials that simply conduct electricity, these perovskite crystals physically bend in response to light, a behavior that can be reversed once the light is removed. This discovery opens the door to developing new light-controlled devices and sensors.<\/p>\n\n\n\n

The team, led by graduate student Mansha Dubey, found that the intensity and color of light used could precisely control the shape change of the crystals. <\/p>\n\n\n\n

The crystals undergo a shift in their internal structure when illuminated, and this effect, called photostriction, can be repeated many times. The ability to fine-tune the amount of bending with light could lead to innovations in smart materials that respond dynamically to external stimuli.<\/p>\n\n\n\n

This breakthrough is significant because it allows for light to manipulate the physical properties of materials, unlike traditional semiconductors. <\/p>\n\n\n\n

These materials could be used in future optical sensors, actuators, and even light-powered computing devices, offering more efficient and flexible alternatives to current technologies.<\/p>\n\n\n\n

Perovskite crystals are already used in solar cells and optoelectronics due to their cost-effectiveness. Now, their ability to change shape with light adds an entirely new dimension to their potential applications. <\/p>\n\n\n\n

The findings could have far-reaching impacts on the development of light-driven technologies and next-generation computing systems, where light replaces electricity in manipulating materials.<\/p>\n\n\n\n

The research was supported by the Defense Advanced Research Projects Agency (DARPA) and the National Science Foundation and marks an exciting advancement in materials science. <\/p>\n\n\n\n
