Dr Divya Chaturvedi, Assistant Professor, Department of Electronics and Communication Engineering, has come up with an exciting proposal for enhanced connectivity and high-speed data transmission across the Internet of Medical Things (IoMT) devices. Her research paper titled “Design of Antenna-Multiplexer for Seamless On-Body Internet of Medical Things (IoMT) Connectivity” has been published in the journal ‘IEEE Transactions on Circuits and Systems II: Express Briefs’, having an impact factor of 3.71. It was published in collaboration with Dr Arvind Kumar from Vellore Institute of Technology and Dr Imaculate Rosaline from Ramaiah Institute of Technology, Bangalore.

The research looks into the design and development of a multi-band self-triplexing antenna for Medical Things (IoMT) applications. The antenna is designed to operate at 5.2, 5.5 and 5.8 GHz and self-isolation is achieved below -23.9 dB. It also offers seamless communication links to other devices operating at the same frequencies. The designed antenna is cost-effective and compact in size, that can easily fit into any implantable medical device. To avoid the harmful effect of radiation, the SAR value should be <1.6 W/kg. The SAR for this antenna is achieved at 0.362 W/kg in a very simple profile. Due to its compact size, the antenna can be easily mounted in a wireless portable device. The self- triplexing property of the device also enables full-duplex communication between different devices in a single antenna. This design suggestively simplifies the density of the RF front-end subsystem and leads to a simple and efficient communication system.

Abstract of the Research

Here, a compact design of antenna-multiplexer is engineered specifically to meet the stringent requirement imposed by intricate subsystems operating at 5.2, 5.5, and 5.8 GHz frequency bands for Internet of Medical Things (IoMT) applications. The proposed design includes a hexagonal-shaped substrate integrated waveguide (HSIW) cavity, tripole-shaped radiating slot, tuning vias, and three inset microstrip feedlines. A tripole-shaped slot is imprinted on the top of the SIW. This slot subdivides the cavity into trio-radiating segments and each segment offers a single frequency band. Further, the frequency bands are tuned at 5.2/5.5/5.8 GHz. The design maintains mutual port isolation better than 23.9 dB. Compared with the conventional tri-frequency antennas, the proposed design is highly compact and doesn’t need any additional circuitry to improve the port isolations. The measured results confirm the expected performance of the design. Furthermore, the proposed antenna is optimized within an implantable medical device (IMD) and simulated inside a realistic Human Head model at a depth of 3 mm and the Specific Absorption Rate (SAR) value is estimated. The SAR values are well below 0.362 W/Kg at the functioning bands due to the unidirectional radiation pattern from the antenna.

Her future research plan includes designing and developing a cost-effective bra-like prototype of Antenna-Array Sensors for breast cancer detection.

The SRM University-AP team met Dr. Tata Narasinga Rao, Director, International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI, Hyderabad) on 7 April 2022, Thursday. ARCI is an internationally acknowledged autonomous body under the Department of Science and Technology (DST), Government of India. Ten professors, led by SRM University Pro-Vice-Chancellor, Prof. D Narayana Rao, went to Hyderabad to meet the ARCI Director. Projects related to key advanced materials in the field of scientific research were discussed during the meeting. Discussions were held on research projects related to additive (3D) manufacturing, solar energy materials, automotive energy and nanomaterials. The SRM AP Professors; Prof. D Narayana Rao, Prof. G S Vinod Kumar and Prof. Ranjit Thapa explained the key points of the research to the ARCI Director. During the event, an understanding was reached on issues such as research partnership between the two organisations and the design of research facilities. Director Dr. Tata Narasinga Rao assured that ARCI would extend full cooperation in areas such as research assistance in the selected fields and provide other facilities. Prof. Narayana Rao affirmed that ARCI has agreed to provide necessary funds for the development of solid electrolytes used to manufacture Lithium Ion batteries.

paper publicationMindfulness, leadership, and performing arts have deep interconnections that, if approached theoretically, can give productive outcomes to implement in workplaces and potential employees. The School of Entrepreneurship and Management Studies is delighted to inform you that the paper titled ‘Exploring mindfulness and leadership development: Lessons learned using grounded theory through the study of the performing arts’ by Dr Vimal Babu, Associate Professor, got published in the journal FIIB Business Review published by SAGE publication.

Abstract of the research

The research looks at mindfulness mechanisms and leadership characteristics as they are expressed in performing art forms. This qualitative study examines major categories to create a theoretical framework for mindful leadership development using performing arts. The present study employs the research paradigm of interpretivism to investigate respondents’ experiences and unique phenomena. The Grounded theory (GT) methodology helps explore grounded data and the development of theories. The abstract core category ‘Immense Concentration and Self-Control’ captures the abstract and inclusive meaning as understood by the sample respondents. The qualitative coding analysis aided in the investigation of the data-driven abstract phenomena. According to the findings of this study, all performing artists require a higher level of attention and self-control to demonstrate fascinating performances like Koodiyattam. A higher level of attention and self-control can be ensured based on increased mindfulness, identified leadership attributes, motivation components, values and beliefs, and personality dispositions of the performing artists. In-depth theoretical reflections on the relationships between the relevant categories are presented. The relationships between the five major categories of mindfulness processes, leadership abilities, motivation components, values and beliefs, and personality dispositions are very significant.

Explanation of the research

In simple terms, the present research explores the dynamics of mindfulness, leadership, and other potential variables enabling mindful leadership through performing arts, helping the practicing managers learn the innovative approaches to inculcate mindful leadership in employees in the workplace. To attain the research purpose, researchers studied the Koodiyattam performing arts as an instrument of mindfulness and leadership based on in-depth interviews of Koodiyattam performing artists. Since the present work explores deeper meanings and experiences to unearth unique and insightful phenomena, the Grounded Theory was appropriately employed as a methodology.

Practical implementation of the research

Managers and executives can derive valuable insights based on the present study. They would be able to understand the interconnections of mindfulness, leadership, and performing arts. It would offer them a better grounding to argue and introduce arts-based initiatives at their workplaces to enhance mindful leadership amongst potential employees aiming for well-being and career development in the organization. Several organizations have been experimenting with arts and its impact on business. However, the studies are in the nascent stage. Hence, more like-minded researchers need to join hands for diverse, global, and intercultural studies, focusing on different variables, including arts. The findings of the present research exhibit firm conviction in enlightening the industry practitioners to consider performing arts based mindful leadership training to enhance mindfulness and leadership attributes of the employees, in turn, making them productive and engaged workforce in the long run.

For this research, Dr Vimal babu has collaborated with Dr Amresh Kumar, IIM, Bodh Gaya, India, and Vipin Kumar, PMP, BT India, Gurgaon, India. His future research plans are to work in strategic leadership, negotiation, and conflict management using innovative qualitative research methods. Entrepreneurship education and circular entrepreneurship are also an area of much interest.
