Mobile keyboards and regular laptops are quite large and bulky.

Keemin Sohn researchers, Ji Sik Kim, Kee-Sun Sohn - the project leader stated that the new ultra-thin nano rubber keyboard works perfectly, even better than conventional portable keyboards. both in function. Not only is it better, more convenient for moving but this device is also very cheap, only about 1 USD (more than 20,000 VND) each so users can easily replace it if it is broken.
