Researchers have unveiled a smart material that reacts to both heat and electrical stimuli. This breakthrough was reported by the University of Waterloo. The development centers on an inexpensive fabric crafted from polymer nanocomposite fibers derived from recycled plastic. The fabric can shift color and shape in response to environmental changes, thanks to a specialized loom that merges polymer composites with stainless steel threads. It operates at a low voltage of five volts, making it safe to wear and enabling efficient, compact control over its behavior.
Upon heating and the application of an electric field, the fabric changes color and returns to its initial form. By weaving and selectively activating fibers with different starting shapes, the fabric can be steered to produce desired movements. The researchers suggest this invention could enhance virtual reality experiences by allowing clothing to simulate contact with the surrounding space. In addition, potential applications include automotive components such as bumpers that can revert to their original shape after a collision, illustrating a path toward adaptive, self-restoring materials.
Researchers also note potential advances in biomedical contexts, including explorations into memory impairment related to Alzheimer’s disease in animal models. While early, these findings point to promising directions for therapies that could influence neural function and recovery in complex conditions. [Citation: University of Waterloo]
