## Meet the editor

Bhaskar Dudem is currently working as a Post-Doctoral Research Fellow (from Oct 2019) at the Advanced Technology Institute (ATI), University of Surrey, England, UK. He received a Master of Technology (MTech., 2012) from the Department of Materials Science and Engineering, Indian Institute of Technology (IIT) Kanpur, India. Afterward, he was a teaching faculty member at K.L. University, India (2012–2014). In August

2018, he received a Ph.D. degree from the Department of Electronics and Radio Engineering, Institute for Wearable Convergence Electronics (IWCE), Kyung Hee University, South Korea. He also worked at the same institute as a Post-Doc for a year (Sep 2018–Sep 2019). His research interests include wearable and flexible piezo/triboelectric nanogenerators for energy harvesting and sensing applications, anti-reflection coatings, and solar, and hybrid energy cells, resulting in more than 30 works published in reputed peer-reviewed international journals.

Venkateswaran Vivekananthan is currently a Research Associate at Advanced Technology Institute (ATI), University Surrey. Prior to joining the University of Surrey, he worked as a Post-Doctoral Associate in the Faculty of Applied Energy Systems (Major in Mechatronics Engineering) at Jeju National University, South Korea. He was a recipient of the NRF Creative Challenge Support award as Principal-Investigator with project

funding worth (USD 45,000/ year). He received his Ph.D. degree in February 2020 with the President Award for outstanding research and academics. His research focuses on energy harvesting using triboelectric and piezoelectric nanogenerators for self-powered sensor systems.

Arunkumar Chandrasekhar, Ph.D., is currently an Assistant Professor in the Department of Sensors and Biomedical Technology, Vellore Institute of Technology, India. He worked as a postdoctoral researcher at the Nanomaterials and Systems Laboratory, in South Korea. He obtained his Ph.D. in Mechatronics Engineering from Jeju National University, South Korea, where he was a recipient of a scholarship from the Korean Govern-

ment Scholarship Program. Dr. Chandrasekhar also received the prestigious "Brain Korea 21+" Business Research Award from the Ministry of Education for excellence in research work. He is interested in wearable triboelectric nanogenerators, battery-free electronic devices, energy storage devices, microelectromechanical systems, and self-powered devices.
