• Voice intelligibility in a noisy environment
• Convenience of wearing (when integrated onto another worn article such as a helmet)
• Unobtrusive compared to a close talking boom microphone
• Waterproof and heat resistant

The BU Series piezo-ceramic accelerometer has output from 20 Hz to above 10 kHz, and is used primarily as a contact microphone for high noise environments. It may also be used as an accelerometer with lightweight structures.

As a contact microphone, the BU may be worn on the throat, or touching a bony part of the head (top, temple, or mastoid bone). BU has been integrated into helmet designs for radio communication for military and emergency services.

• High frequency functionality
• Wide range of applications
• Micro-sized sensing and actuation

Derived from our industry-leading MEMS silicon surface mount microphone technology, our new ultrasonic sensor designs function on a high frequency band. Sensor designs are possible across a wide spectrum of applications requiring highly miniaturized solutions for sensing and actuation/signaling.
