Partnering opportunity

A Turkish researcher offers mechanical thermal camera to licence the technology

Summary

A Turkish researcher has developed an MEMS (micro-electro-mechanical systems) thermal camera based on mechanical resonance. Unlike other thermal cameras, the image is obtained by mechanical vibrations of pixels. Thus it has wider dynamic range, higher resolution and lower power consumption compared to other available thermal cameras. The researcher is looking for opportunities to license the technology.

Partner sought

The inventor is looking for companies who are operating in defence & security with the purpose to license the technology.

Description

MEMS (micro-electro-mechanical systems) thermal camera that is based on mechanica resonance has developed by a Turkish researcher and originated from Turkey. Thermal imaging has been commonly used in agriculture, defense and non-military industries. High precision and resolution together with low power consumption and miniaturization of these thermal cameras are common needs of these sectors. With the implementation of the proposed camera focal plane array structure, there is an expected improvement in all these needs itemized above. As known, the tunes (the vibration frequency of the strings) of stringed instruments are dependent of the ambient temperature, and thus, counting the frequency, the true temperature of the spring can be obtained. Similarly, with the resonant pixel structures, the frequency shifts due to incident infrared radiation on the pixels will be detected. Counting the shift in the frequency will eliminate the need for an analog-to-digital converter and improve the resolution and dynamic range of the pixel. As a result, smaller pixels, and thus, with the same die size, higher resolution thermal cameras with lower energy consumption will be possible. The researcher is looking for opportunities to license the technology.

Advantages and innovations

In this invention, the thermal image is obtained by determination of the mechanical resonant frequency of pixels. The advantages are as follows; * Improved measurement precision: Continuous measurement of incident radiation (without the need of intermittent cooling) improves the precision. * Frequency based measurement: Measuring the frequency of resonance eliminates the need for an analog-to-digital converter and decreases the power consumption. * The use of structural vibration modes of the pixels: Hence, smaller pixels will be possible. Smaller pixels mean higher resolution in the same die area. * Wide dynamic range: The lowest and highest operational incident infrared radiation is limited by a structural (electronic or mechanical) failure, i.e. not by thermal or electronic saturation. * High frames-per-second (fps) count: Another advantage of continuous measurement is high fps. This is possible because in continuous measurement, there is no need for intermittent cooling of pixels

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
