An innovative wearable device for sensing mechanoreceptor activation during touch
Samples
In order to reflect the difference of tactile perception, 12 samples were chosen with a progressive roughness level. The dataset stems from a single material (ABS), and the surfaces were textured utilising the identical process (laser…

Device enables direct communication among multiple quantum processors
Quantum computers have the potential to solve complex problems that would be impossible for the most powerful classical supercomputer to crack.
Just like a classical computer has separate, yet interconnected, components that must work together,…

Physicists Create New Type of Time Quasicrystal – Inside a Diamond : ScienceAlert
A new type of time crystal could represent a breakthrough in quantum physics.
In a diamond zapped with lasers, physicists have created what they believe to be the first true example of a time quasicrystal – one in which patterns in time are…
