Liquid electromigration in gallium-based biphasic thin films

Stéphanie Lacour, Hadrien Olivier Michaud

Liquid metals have recently gained interest as a material of choice for soft and stretchable electronic circuits, thanks to their virtually infinite mechanical failure strain and high electrical conductivity. Gallium-based thin films are obtained by deposi ...

Stretchable metallization technologies for skin-like transducers

Hadrien Olivier Michaud

The skin is not only the largest human organ, capable of accomplishing distributed and multimodal sensing functions. Replicating the versatility of skin artificially is a significant challenge, not only in terms of signal processing but also in mechanics. ...

Intrinsically Stretchable Biphasic (Solid–Liquid) Thin Metal Films

Stéphanie Lacour, Hadrien Olivier Michaud, Arthur Edouard Hirsch, Aaron Powers Gerratt, Séverine Claire Marie De Mulatier

Stretchable biphasic conductors are formed by physical vapor deposition of gallium onto an alloying metal film. The properties of the photolithography-compatible thin metal films are highlighted by low sheet resistance (0.5 Ω sq−1) and large stretchability ...

Soft metal constructs for large strain sensor membrane

Joan Teixidor, Stéphanie Lacour, Hadrien Olivier Michaud

Thin gold films on silicone display large reversible change in electrical resistance upon stretching. Eutectic liquid metal conductors maintain bulk metal conductivity, even upon extensive elongation. When integrated together, the soft metals enable multid ...

Soft flexion sensors integrating strechable metal conductors on a silicone substrate for smart glove applications

Joan Teixidor, Stéphanie Lacour, Hadrien Olivier Michaud

We design and implement a sensory skin that monitors in real time finger flexure (three sensors per finger) of a user's hand. Compared to current technologies, the electronic skin is made entirely of stretchable materials integrating silicone rubber, low r ...
