Broadband MET Hydrophone

An electrochemical hydrophone based on the principles of molecular electronic transfer (MET) was described. The work presents experimental results for the sensitivity, frequency response and intrinsic noise level. It has been demonstrated the experimental device has 0.8 mV/Pa sensitivity in the frequency band 0.02-200 Hz and low frequency self-noise close to Wenz model. Easy to fabricate, cheap and suitable for mass production the MET Hydrophone could be in demand in marine and tranzient zone seismic survey.
