Current Research Interests

My research focus is based on the use of multifunctional hybrid nanostructures for electrical and electrochemical inspired devices. I am interested in the functional nanoelectronic and energy devices that delivers heterogeneous and versatile applications. My research group is currently focusing on nanostructures synthesis, self-assembled nanostructures for transparent electronics, flexible and stretchable devices, organic hybrid memory, resistive memory, sensors, electrochromics, energy storage supercapacitors and mechanical energy harvestors

Project: Printable Hybrid Mechanical Energy Harvestor

We propose to develop a printable hybrid mechanical energy harvesting (H-MEH). Specifically, we aim at achieving a hybrid device based on piezoelectric and triboelectric technology.  Piezoelectric component will ensure energy harvesting from external mechanical force like ambient vibrations, compressive forces and acoustic energy and triboelectric component will allow energy harvesting from frictional forces and sliding contact. These two components will work in tandem to ensure multiple aspect of mechanical forces present in an industrial environment can be utilized to achieve a higher power density. Fabricating the device using 2D functional printing or 3D printing will ensure easy processability and easy scalability, with advantageous of additive manufacturing. It will also facilitate fabrication of the energy harvesting device of a specific design to suite a specific instrument in an industry. Our target is to improve the total power of ~ 3-5W/m2 with our printable nanocomposite materials for H-MEV.

Project: Integrated Electrochromics for Energy Modulation System in Buildings

Reduction in heat transfer through windows or building roof or envelope can be achieved using electrochromics (EC) modulation of wavelength across the solar spectrum up to wavelengths of 2500 nm. In the low transmittance state, one can minimize solar rays transmitted and maintain indoor thermal comfort with savings on energy expenditure on air-condition, and still retain the view through the glass. Apart from windows, the solar heat gain through roof constitutes a substantial portion of cooling load in air-conditioned buildings. Directional radiation received on the roof can be one of the main causes of thermal discomfort.   When electrochromics are installed on roof surface, the low transmittance state also blocks the reflectance from high glare metal roofs. An electrochromic roof provides an option to modulate indoor heat and light (reduced lighting cost).

On the other hand, we aim to develop a switchable transparent state to mirror (or reflective) state to tailor the visible and thermal near IR wavelength, occupants can also utilize the vertical electrochromic glass door as mirrors when required. This research project serves to develop electrochromic technology to alter the transmittance through windows, doors, and building roofs. A prototype of surface mountable electrochromic foil will be developed for transmissive and reflective modulation purposes.
