About

Srilakshmi Subramanian Periyal is a researcher at the forefront of flexible electronics and self-powered sensing systems. Her primary research areas include triboelectric nanogenerators, microfluidics, and tactile sensing technologies. She is best known for her pioneering work on integrating triboelectric and microfluidic principles to create innovative self-generated tactile sensors. Her most-cited paper, "Triboelectric and microfluidic integrated self-generated tactile sensor" (2017), proposes a flexible sensor that utilizes liquid-solid triboelectric effects to detect both normal and shear forces. This design features four microfluidic channels with multiple underlying electrodes, enabling sophisticated multi-directional force sensing without external power sources. While her citation count is still growing, this work represents a significant contribution to the development of autonomous, flexible tactile interfaces for applications in soft robotics, wearable electronics, and human-machine interaction. Periyal's research bridges fundamental physics with practical device engineering, offering a promising pathway toward truly self-powered, intelligent sensing systems that can operate independently in diverse environments.
