Bionic Hearing

Bionic Hearing

Cat-like 'hearing' with device tens of trillions times smaller than human eardrum. Researchers are developing atomically thin 'drumheads'-- tens of trillions of times thinner than the human eardrum -- able to receive and transmit signals across a radio frequency range far greater than what we can hear with the human ear. Their work will likely contribute to making the next generation of ultralow-power communications and sensory devices smaller and with greater detection and tuning ranges. Source 1h.
