Mochii is a miniature scanning electron microscope created by Seattle-based startup company Voxa. Mochii has the same capabilities as conventional SEM, such as use in materials science for research purposes, quality control of microchips and semiconductors, and medicine. Mochii users can control the microscope using the IOS app.
1. History. (История)
Development of what eventually became Mochii began in 2012. Mochiis goal was to take scanning electron microscopes, usually large, expensive and bulky instruments, and shrink them to reduce cost and increase mobility.
In 2015, Voxa began collaborating with NASA, which saw the potential of putting Mochii into space. Over the past few years, NASA has allocated over $ 450.000 to develop Mochii. MkII had to deal with the problems unique to space operations, such as the "unstable behavior of the liquid, the residual gradients, gravity, cosmic rays and the safety of the flight".
In 2018, Mochii received the Microscopy Today Innovation Award,an industry award given for inventions that make microscopy more efficient and powerful.
In June 2019, Mochii took part in the 23rd NEEMO NASA Extreme Environment Mission Operations mission.
On February 15, 2020, Mochii launched on a Cygnus cargo ship bound for the ISS. The Voxas microscope should help with on-site visualization on the ISS, eliminating the need to send the sample back to Earth, which is associated with problems of cost, time and potential damage to the sample.
2. Technical parameters. (Техническая характеристика)
Mochii measures 21 cm × 21 cm × 26.5 cm and weighs about 6 pounds. The sams stage measures 2 cm × 2 cm × 1.5 cm. Mochii has a replaceable optical cartridge that eliminates the need for personal maintenance. The cartridge has a 10 kV source potential, 5000X magnification, backscatter array detector and automatic calibration. The microscope is capable of EDS, a method that analyzes the energy spectrum of a sample to find out the abundance of certain elements. Mochii comes with an app that runs on Apple devices running IOS 8 or higher.
