A team of students led by Dr. Mostafa Keshavarz Moraveji designs and manufactures a microheater.

A team led by Dr. Mostafa Keshavarz Moraveji succeeds in designing and manufacturing a microheater, a project supported financially by Iran's National Elites Foundation. According to the comprehensive scientific map of the country, nano-technology and micro-technologies are among the country’s priorities of science and technology. Microfluidic systems, due to their small size, in addition to being portable, save materials and energy, time and labor, and reduce the likelihood of human error. Microheaters are widely used, from gas sensors to chip-based laboratory technology and space heating for the synthesis of nanostructures and biotechnologies. Currently, microfluidic research laboratories are the main customers for this high-tech product, and the technical knowledge of the design microfluidersis on the edge of knowledge and will lead to significant advances in microfluidic related fields.

"In general, microheaters are used wherever accurate temperature control is important.", says Somayeh Sohrabi, a PhD student in chemical engineering and the head of the student team. With the development of micro-technology, it became possible to build MEMS electromechanical devices. The applications of these tools in medicine and chemical processes became more diverse due to advantages such as the high ratio of surface area to volume, the possibility of high fluid flow control, and temperature control. In the design of this microheater, the resistance and power consumption were optimized to distribute the temperature evenly. Another advantage of this microheater is the design of the temperature sensor in which it is installed.
"NanoSniff, Murata, and Dolomite are the manufacturers of microheaters abroad.", added Dr. Mostafa Keshavarz Moraveji, the team leader. This technology has not been localized in Iran and there is no manufacturer of microheaters in the country, and companies that work in the field of microfabrication are only able to create chips and do not produce microheaters with a control system. The team has the ability to produce microhear with a control system similar to foreign models at one-fifth of the cost.
The student team members are Somayeh Sohrabi, Leila Haj Shah Valadi, Farnaz Dana JamalAbad, Seyed Mohammad Amin Ojagh from Amirkabir University of Technology (Tehran Polytechnic) and Farnaz Heidarpour from
Iran University of Science & Technology.
The project has been featured in an IRIB TV program (Channel 5) and can be viewed through this link: https://www.telewebion.com/episode/2601624
