Tiny ‘hearing’ device is 100,000 times thinner than your eardrum

The paper, published in the March 30th issue of Science Advances, says that the super small vibrating sensor can detect signals at the highest reported dynamic range of frequencies, up to ~110dB, at radio frequencies (RF) up to over 120MHz. Human hearing is generally in the range of around 60 to 100dB in the range …
