SORI: A softness-rendering interface to unravel the nature of softness perception
Jamie Paik, Mustafa Mete, Hwayeong Jeong
Tactile perception of softness serves a critical role in the survival, well-being, and social interaction among various species, including humans. This perception informs activities from food selection in animals to medical palpation for disease detection ...
Natl Acad Sciences2024Additively manufactured stretchable zipping electrostatic actuators
The use of soft and stretchable materials allows the development of adaptive robotic systems and human-machine interfaces that are more natural and comfortable to interact with. One of the application fields that benefits the most from these compliant mate ...
EPFL2024Carbon based printed electrodes for DEAs: study of pad, inkjet, and stencil printing
Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Stefania Maria Aliki Konstantinidi, Armando Matthieu Walter, Simon Holzer
Dielectric elastomer actuators (DEAs) have raised interest due to their remarkable capabilities in various applications, such as soft robotics, haptic feedback systems, and biomedical devices. To harness the full potential of DEAs, the choice of the electr ...
Society of Photo-Optical Instrumentation Engineers (SPIE)2024Hydraulically Amplified Electrostatic Taxels (HAXELs) for Full Body Haptics
Herbert Shea, Edouard Franck Vincent Gustave Leroy
The ability to mechanically stimulate touch receptors over the entire body is a key feature for fully immersive and highly realistic virtual reality experience. Haptic stickers, flexible arrays of HAXELs (hydraulically amplified TAXels), that enable cutane ...
WILEY2023Liquid Metal-Based Sensor Skin Enabling Haptic Perception of Softness
Stéphanie Lacour, Ivan Furfaro, Emilio Fernández Lavado, Haotian Chen
Haptic perception of softness is a unique feature of the human skin that relies on the concurrent measurements of the lateral deformation and compression of the skin during object manipulation. This is challenging to implement in robotics because of combin ...
2023Dynamic control of high-voltage actuator arrays by light-pattern projection on photoconductive switches
Herbert Shea, Amir Firouzeh, Edouard Franck Vincent Gustave Leroy, Vesna Bacheva, Aiste Balciunaite
The ability to control high-voltage actuator arrays relies, to date, on expensive microelectronic processes or on individual wiring of each actuator to a single off-chip high-voltage switch. Here we present an alternative approach that uses on-chip photoco ...
SPRINGERNATURE2023PopTouch: A Submillimeter Thick Dynamically Reconfigured Haptic Interface with Pressable Buttons
Herbert Shea, Amir Firouzeh, Ayana Mizutani
The interactions with touchscreens rely heavily on vision: The virtual buttons and virtual sliders on a touchscreen provide no mechanical sense of the object they seek to represent. This work presents PopTouch: a 500 mu m thick flexible haptic display that ...
Weinheim2023Time Reverse Impulse Demonstrator Force Sensing Surface
The goal of this project is to design, build and test a 3D touch-sensing interface prototype capable of reading input positional and force values that then generate sinusoidal sound waves. This prototype is intended to be integrated onto a haptic feedback ...
2022Changing Finger Movement Perception: Influence of Active Haptics on Visual Dominance
Ronan Boulic, Bruno Herbelin, Loën Boban
The perception of one’s own body is a complex mechanism that can be disturbed by conflicting sensory information and lead to illusory (mis-) perceptions. Prominent models of multisensory integration propose that sensory streams are integrated according to ...
2022Foot-Interfaces Control and Human-Robot Interaction in Four-Handed Manipulation
Humans have a great capacity to perform complex manipulations. However, there are many tasks for which two hands are not enough, such as in surgery. For such tasks, a dyad of people is required. However, when not used to work together, a dyad collaboration ...
