Development of Sensor Interfaces,
Analog-to-Digital Converters,
Measurements, and Instrumentation.
My research focuses on the field of Instrumentation and Measurement, with particular emphasis on the development of sensor interfaces and measurement systems for capacitive and magnetic sensors. Since my appointment as an Assistant Professor at IIT Tirupati in 2017, my work has expanded from capacitive sensors to include a broader range of sensor technologies, including magnetic and piezoelectric sensors. These sensors play a critical role in various applications such as proximity detection, current measurement, and structural damage assessment, among others.
One of the core aspects of my research during my PhD has been the design and development of Capacitance-to-Digital Converters (CDCs), which offer a direct digital output from capacitive sensors without the need for additional analog-to-digital converters. These converters have applications in proximity detection, motion sensing, and environmental monitoring. Recent work with my students has introduced novel interface circuits that enhance the performance of capacitive sensors, particularly for direction detection of humans. We have successfully developed systems that are low-power and cost-effective while providing high accuracy and robustness to noise and sensor imperfections.
Building on my experience with capacitive sensors, my research has now extended into magnetic sensors for non-invasive current measurement. This has led to the development of new probe designs for measuring currents in concealed conductors, which is highly relevant in electrical safety and maintenance scenarios. These magnetic sensor-based systems are not only innovative in their design but also demonstrate a high degree of accuracy and resolution, making them suitable for a wide range of current measurement applications.
In addition, I have established an Electronic Instrumentation Laboratory at IIT Tirupati, which serves as a hub for research on advanced sensing technologies. This facility allows scholars to experiment with various sensor architectures and develop industry-relevant solutions, further enhancing the research ecosystem at our institution.
Looking ahead, I am eager to explore opportunities for collaboration with researchers and industry partners who share an interest in advancing sensor technologies and measurement systems. By investigating new materials, sensor architectures, and signal processing techniques, I aim to contribute significantly to academia and industry in fields such as industrial automation, structural health monitoring. I welcome discussions on potential research projects and partnerships that can leverage our collective expertise and drive innovation.
