Prof. Bae Jin-ho develops nano power generating device 

An electric nano-power generating device that can be used as an auxiliary power source for various portable wearables and bio-transplant electronic devices even in poor environments has been developed by researchers at Jeju National University.

Bae Jin-ho, a professor of marine system engineering at Jeju National University (head of the BK+ Big Data-Based Marine Convergence Professional Team), developed friction electricity and piezo-electric nanogenerating devices using Metal-Organic Frameworks (MOF-5) materials. The development was achieved through joint research on convergence in cooperation with Jeju National University’s Research Institute of Basic Science.

Friction electric nanogenerators are devices that can convert mechanical energy into electrical energy by using charging phenomena that occur when two objects are in contact or friction. Piezo-electric nanogenerators are devices that can produce electrical energy using a phenomenon in which positive and negative charges proportional to external forces appear on both sides of the plate when pressure is applied to the crystal plate in a certain direction.

MOF-5 is useful for developing electronic devices with excellent thermal and chemical stability, adjustable porosity, and high surface area. Related studies are being conducted to develop electronic devices that are resistant to poor surroundings.

Using MOF-5 materials, Prof. Bae’s team proved the applicability of two power-generating devices: a friction electric nanogenerating device and a piezoelectric nanogenerating device.

In particular, the research team explained that MOF-5 materials were applied to show that they could be used as a stable electrical energy source for electronic devices in poor environments with high temperatures and humidity.

The research findings were published in Nano Energy (Vol. 96, Impact Factor, citation index of 17.881), a world-renowned international journal. The paper is titled, “‘Ultra-robust tribe- and piezo-electric nanogenerator based on metal-organic frameworks (MOF-5) with high environmental stability” (corresponding author Bae Jin-ho, lead author Shaukat Riyan Ali, co-author Sakib Kazi Muhammad).
