Tiny, high-precision actuators and micro-mechatronic modules are enabling a wide range of next-generation defense and security systems. These include:  

• Biometric detection from a distance. Miniature focus modules in cameras for facial scanning and iris scanning enable a much greater variation in the distance from target subject to the camera for biometric identification. Applications include keeping the line moving at airport security points. Other biometric applications include hands-off instrument control using eye tracking as the user interface, and IR cameras. Learn more about biometrics applications.
• Active tuning for extended communications bandwidth. Miniature linear motion modules are used to create smaller, high-power RF and microwave tuning circuits for field-tunable base station transmitters and receivers, delivering extended communication bandwidth. Target applications include spectral tuning systems and software defined radio. Learn more about tuning applications.   
• Biological and chemical detection. Field-portable spectroscopy and flow cytometry systems use miniature actuators to control gratings for precision wavelength selection, while keeping the systems small and lightweight with lower power use.  
• Missile and munitions controls. Custom rotary actuators offer high torque, high speed and high precision in extremely thin packages. The non-magnetic actuators will not interfere with magnetometer (GPS) navigation systems. See the proof of concept.

Other defense and security applications include laser targeting, active stabilization, UAV / UAB controls and fiber alignment. Piezo actuators and closed-loop modules enable systems that are small, lightweight, low power... and extremely precise.
