About

Betty Lemaire-Semail is a leading researcher in haptic perception and tactile neuroscience, whose work bridges the gap between physical interactions and human sensory experience. Her key research areas include tactile perception, friction dynamics, and the neural underpinnings of active and passive touch. She is best known for her groundbreaking study on "The tactile perception of transient changes in friction" (2017, 66 citations), which revealed how subtle frictional strains during surface exploration are perceived—critical knowledge for advancing interactive displays with haptic feedback. This work has become foundational for the nascent industry of touch-based interfaces. In another notable contribution, she developed a novel EEG method to characterize cortical processes during active versus passive touch (2016, 13 citations), using steady-state evoked potentials to map brain responses to identical tactile stimuli. This innovation provides unprecedented insight into how motor intent shapes tactile perception. Her research has profound implications for haptic technology, prosthetics, and human-computer interaction, establishing her as a pivotal figure in understanding the neural and physical mechanisms of touch.
