Research Interests

The focus of my research is on making of novel sensors and actuators for a wide range of applications with emphasis on sensors for medical applications and agricultural robotics. With a special emphasis on using 'smart and functional materials' in developing sensors and actuators, I encourage interdisciplinary approach to develop knowledge and bring together the advancements from across various fields (chemistry, biology, electronics) into the design.

With the need for manipulating and fabricating sensors and actuators from these smart materials, my research also focuses on development of novel fabrication techniques that can suitably handle these smart materials to preserve their functional properties. In these lines, development of 4D printing capabilities is also my area of research.

My research areas are

  • Developing novel sensing techniques (biomedical sensing, force, torque, pressure, strain, flow and optical)
  • 4D printing of SIA (sensor integrated actuator) designs.
  • Wearable medical devices.
  • Rehabilitation robots (exoskeletons).
  • Process automation.
  • Environment mapping (SLAM).
  • UAV flight dynamics.
