His work focuses on innovative devices that enhance the accuracy and efficiency of measuring shear stress and pressure.

Latest Patents

One of Haritonidis's latest patents is a shear stress measuring device. This device utilizes a micromachined diaphragm positioned across a gap from an end of an optic fiber. The diaphragm and optic fiber are integrally mounted, allowing the end of the optic fiber to serve as a local reference plane. Light carried through the fiber is split into transmitted and locally reflected parts, which then interfere to form an interference light pattern. This pattern is carried back through the fiber to a light detector, providing an indication of diaphragm deflection based on applied pressure. A second fiber positioned across the gap further enhances the detection of diaphragm deflection, allowing for precise measurement of both magnitude and direction. An opening that enables communication between ambient conditions and the gap allows the interferometer sensor to function effectively as a shear stress measuring device.

Another significant patent by Haritonidis is a pressure transducer apparatus, which shares a similar design and operational principle with the shear stress measuring device. The micromachined diaphragm and optic fiber configuration allows for accurate pressure measurements through the same interference pattern mechanism. This innovation has broad applications in various fields requiring precise pressure sensing.
