The boost in the technology of in-ear devices (hearing aids and hearing protection devices) make them much smaller and more effective today. One of the most challenging issues in this regard is finding the suitable sources of power. Batteries as the traditional source of power have some disadvantages including large volume and limited lifetime. Moreover, they are very expensive and impose high operating costs to customers. Energy harvesting is a promising alternative method to replace batteries, decrease the operating costs and bring more convenience for users. In an energy harvester, the energy of ambient vibrations like the normal motion of the human body is scavenged, saved and used to power device. As a postdoc researcher, I am investigating energy harvesting mechanism to apply for the hearing devices based on Micro-Electro-Mechanical systems (MEMS).

Microcantilever-based sensors and actuators

Nowadays, you usually hear about nano-science and nano-technology everywhere as a new millennium technology, but have you ever thought that how scientists can see objects in nano-meter scales? You may guess that they use professional optical microscopes to see nano entities, but it is amazing to know that objects in nano-scale can never be seen by optical microscopes even the strongest and the most sophisticated ones, so what they can do? Atomic Force Microscopes (AFM) are one of the most promising solutions to this challenge. AFMs use the interaction force between the microcantilever-tip and sample to create a topographical or virtual images of objects in nano-scales. In addition to this sensing tasks, microcantilever tip can also be used as a robotic arm to move or manipulate nanoparticles and nanoentities. I have been working on microcantilever-based sensors and actuators for several years as a PhD thesis. I succeeded to present a reliable nonlinear distributed-parameters modeling of microcantilevers subject to the tip-sample interaction force. The theoretical analyses well agree with my experimental investigations and the results have been published in several accredited journals. This is an important step toward automatic nanomanipulation frameworks which is the most versatile tool for manipulation of bio-materials like DNA, Proteins and etc.

Generator air/water heat exchanger test unit

I collaborated in design, install and control of the heavy-duty air-water cooler test unit for generators in hydro-plants. It is a unique test plant which does not have any counterpart in size and capacity in Iran.
