Space Station Crew Can Do Bio Experiments Thanks To SETi's UV LEDS

High power LEDs decontaminate surfaces, liquids and air inside experiment 'glovebox'

Conducting science experiments in space aboard the International Space Station, presents many challenges from working in a microgravity. But thanks to the Microgravity Science Glovebox (MSG), those aboard the space station have been able to safely conduct their experiments since 2004.

Over the past ten years, the MSG has been put to good use on a wide range of research programs but now, thanks to the activation of a new decontamination system inside the MSG, crew members can safely perform biological research.

Developed and built by Teledyne Brown Engineering (TBE) the decontamination system makes use of high-power Uvclean ultraviolet LEDs developed by Sensor Electronic Technology Inc (SETi) in part through the DARPA Compact Mid-Ultraviolet Technology (CMUVT) program.

The UV LEDs have the power to sanitise the surfaces, liquids and air inside the MSG in a matter of minutes and are used before and after the experiments are conducted for the safety of the crew. 

The upgraded MSG with TBE's decontamination system and SETi's UV LEDs will allow for a much wider range of microgravity experiments and will be available to all biological payloads that operate in the MSG with a concern about contamination. 

"Our products passed space flight qualification in the past", commented Remis Gaska, president and CEO of SETi, "However, this is the first space launch, installation and successful testing of our devices in the orbit. This demonstrates the level of maturity of Deep UV LED technology". 

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
