A Compact integrated Electro-Optic Based Interferometer
Introduction Interferometry uses the principles of constructive and destructive interference to combine two or more waveforms, such as light, to form a phase-dependent source of the two signals. It is used to compare light from two or more sources to obtain measurements with higher resolution and precision than could be obtained by conventional direct methods. Technology description Researchers at the UW have developed a compact integrated electro-optic based Fabry Perot interferometer, utilizing both the high speed and low voltage operation of polymer based electro-optic material and high resolution wavelength scanning. The advantages of this design are its compatibility with many different substrates, low cost and ease of fabrication. The driving voltage in the single or double digits range is also ideal. Business opportunity The UW Electro-optic interferometer sensor was developed to measure pressure and shear stress on the sole of the foot, with emphasis on diabetic neuropathic patients. Other applications include monitoring building infrastructure, biomechanics, or robotics. It can be used to monitor relatively large and irregularly shaped areas, and has the potential to be used to drive actuators to respond to varying pressures on an object, creating truly intelligent designs. Stage of development The sensor has been prototyped and initial data exist for this technology. Intellectual property position The UW is currently reviewing this technology for worldwide patent protection.Type of Offer: Licensing
