Prof. Jaeyoung Park's Research Team (Department of Electronic Engineering) Won IEEE MEMSPower MEMS International Conference Paper Award
Professor Park Jae-young's research team (Electronic engineering department) won the Best Paper Award (Poster Category, Kumar, combined masters & doctorate course) at the ‘21st Micro and Nanotechnology for Power Generation and Energy Conversion Applications 2022’ held in Utah, USA from December 12 to 15, 2023 held by Institute of Electrical and Electronics Engineers (IEEE). The research team also won the Best Paper Award (Oral Presentation Category, Saebung Jang, doctoral course) at the ‘36th Micro Electro Mechanical Systems 2023’ held in Munich, Germany from January 15th to 19th, 2023.

The paper presented
by Kumar is an eco-friendly energy storage technology that reduces energy loss
and simplifies complex circuits by integrating nanogenerators and energy
storage devices without a separate rectifier circuit. In
this study, a self-charging Supercapacitor Power Cell (SPC) in which a Triboelectric Nanogenerator
(TENG) and a supercapacitor for energy storage are combined into one unit was
developed. Since the electrical energy generated by the TENG is stored in the
supercapacitor without a rectifier circuit, energy loss is greatly reduced. In
addition, the TENG portion of the self-charging SPC can generate 2.5 mW of
power, which can charge the SPC to a maximum voltage of 210 mV within 9
seconds. Meanwhile, this study was carried out with the support of the Ministry
of Science and ICT's Mid-sized Research Project (NRF 2020R1A2C2012820) and the
Ministry of Trade, Industry and Energy's Industrial Technology Development
Project (RS-2022-00154983).

The paper presented by Saebung Jang is a self-powered toroidal triboelectric sensor (STTS) technology. By using the 3D printing technology to create a minimum space between the finger skin and the cathode triboelectric layer, the pyramidal arrangement of MXene/Ecoflex nanocomposites has simplified the manufacturing process of the pressure sensor while improving its performance and greatly improving wearability. The developed STTS exhibited high flexibility, high triboelectric peak-to-peak voltage (19.91 V) output, high sensitivity (0.088 VkPa-1), and wide pressure detection range (0-120 kPa). STTS can be easily worn on the finger to accurately detect various finger movements and human-machine interface (HMI) controls for virtual reality gaming. Meanwhile, this study was funded by the government (Ministry of Trade, Industry and Energy) through the Industrial Innovation Talent Growth Support Project (P0002397) of the Korea Institute for Advancement of Technology and the Industrial Technology Transformation Project (RS-2022- 00154983).
