Magnetoelectric #antenna aims to boost #underwater comms 800 billionfold
#BlueME's key innovation is a #MagnetoelectricAntenna, a magnetic field deforms a magnetostrictive layer made from material called #Metglas, mechanical deformation induces a voltage in an adjacent piezoelectric layer (PZT, a common ceramic used in sensors and actuators). Run process in reverse, and you have a transmitter. Result is an antenna that operates at very low frequencies, around 35–36 kHz.
