A device for use in detecting an event in a structure includes a sensor
encapsulation, the encapsulation containing a sensor, an actuator
positioned substantially in-plane to the sensor within the housing and a
printed circuit board in communication with at least one of the sensor
and the actuator. The printed circuit board includes a microprocessor
constructed and arranged to collect data from at least one of the sensor
and the actuator, a signal generator constructed and arranged to provide
excitation to at least one of the sensor and the actuator, and an
amplifier to condition the excitation.
