Abstract
Transducer comprises an optoelectronic switch embedded in epoxy resin in a cylindrical cavity and with an integrated amplifier. An electroluminescent diode and a silicon photodiode with optical reflection based coupling, monitor earthquake-susceptible material located on a base-plate via a spring. A slit between the diodes modulates the vibration.
