Kitchen sponges can be used as memory devices
Study shows potential for helping mimic architecture of the human brain
When Harsh Jain, at the National Centre for Biological Sciences in Bengaluru, squeezed a kitchen sponge cube between two metal plates, he could imprint external deformities in the shape of alphabets using a motorised rod. Potential applications of the study findings also include the fabrication of auxetics, unusual materials that widen when stretched and narrow when compressed, and reprogrammable Braille displays that require systematically creating deformation patterns. However, IISc’s Gondi Kondaiah Ananthasuresh recommends further exploration beyond the basic friction model outlined in this paper because mechanical properties, although common in everyday objects, such as light switches and latches, exhibit complex behaviour at the microscopic or atomic scales.
