About
Dr. Withanage K. Perera is a pioneer in the development of imperceptible, wearable biosensors for human-machine interfaces. His research primarily focuses on graphene-based electrooculography (EOG) systems, which record the electrical potential between the cornea and retina to track eye movements. Perera’s most cited work, "Imperceptible electrooculography graphene sensor system for human–robot interface" (2018, 155 citations), addresses a critical limitation of conventional EOG sensors—their bulkiness and discomfort. By engineering a flexible, graphene-based sensor that is nearly invisible to the wearer, he enabled seamless, long-term eye-tracking for robotic control without hindering natural movement. This breakthrough has profound implications for assistive technologies, allowing individuals with motor impairments to operate robots or communicate through eye gestures. Perera’s contributions bridge materials science and biomedical engineering, demonstrating how atomically thin materials can revolutionize human-robot interaction. His work has been widely cited in the fields of wearable electronics and neural interfaces, highlighting its impact on creating more intuitive, comfortable, and accessible control systems for next-generation robotics.
