Abstract
A method and geophysical acceleration sensor () for measuring seismic data and also for protecting the sensor from shock. The sensor includes a housing (); a flexible beam () having a first end fixedly attached to the housing; a piezoelectric layer () attached to the flexible beam; a seismic mass () attached to the flexible beam; and a first movement limiter () connected to the housing and configured to limit a movement of the flexible beam. A distance between a tip of the first movement limiter and the flexible beam is adjustable.
