Researchers propose ‘beautiful’ nanoscale sensors

Friday, June 30, 2017

Researchers at Waterloo Engineering have developed a new conceptual method for measuring extremely tiny objects, potentially paving the way for super-sensitive sensors capable of powering themselves.

Hassan Askari and Ehsan Asadi, both mechanical engineering PhD candidates, showed that nanoscale devices using electromagnetism could determine the mass of objects a hundred billion times lighter than a strand of hair.

“The concept is very beautiful,” said Askari, who is supervised by professors Amir Khajepour and Behrad Khamesee.
