    3 years contract starting on January 1st 2023 at CY Cergy Paris Université (France)


    The Marie Skłodowska-Curie Actions Doctoral Network SOFTWEAR (SOFT actuators for Wearables, Exoskeletons, and Augmenting Robotics) will comprise 12 PhD students from 10 European Universities. SOFTWEAR is a highly interdisciplinary Doctoral Network in the emerging and rapidly growing field of wearables, with a unique focus on soft actuators for wearables and exoskeletons. The primary objective of SOFTWEAR is to train young researchers in the multidisciplinary science of soft actuators for integration in wearables and augmenting textiles. This will be achieved by merging chemistry, physics, mechanics, electronics, textile technology, design, human-technology interaction and ethics in a truly interdisciplinary manner, while teaching essential skills in ethics, product development, IPR and industrial realisation, thus providing a unique added value to the careers of the Researchers. This will be accomplished by on-the-job training on innovative research projects developing beyond-the-state-of-the-art soft actuator technology and integrating this into active garments and soft exoskeletons. The research will be carried out at leading academic groups and by immersion in applied projects at the industrial partners. The position will require traveling to participate in Training Schools and secondments of several months to academic and industrial associated partners.

    Research Project

    Electroactive yarns that could exhibit large contractile stroke and operate in open-air are strongly desired as actuating element of actuating textiles and garments. Among the different artificial muscle technologies, carbon nanotube (CNT) yarn muscles are especially promising because of their electrical control, low activation voltage and high electronic conductivity. They rely on the charging/discharging of the electrochemical double layer (EDLC) at the CNT-electrolyte interface through capacitive process, transducing a low- voltage electrochemical stimulation into mechanical response. Interestingly, when the neat CNT yarns are coiled by overtwisting, their spring-like structures can convert torsional electrochemical actuation into large tensile deformation. By combining two CNT yarns, respectively acting as anode and cathode, with an ionic conducting gel, it becomes possible to develop contractile yarn muscles operating in the open-air 1.

    The project of the recruited PhD student aims at developing CNT yarn muscles for actuating textiles. He/she will first develop the ionic conducting coatings that will act as the ion source for open-air operation. The targeted materials will be ionoelastomers combining stretchability, toughness and ionic conductivity in the “dry” state, i.e. without containing any liquid phase or solvent. It will be achieved by the synthesis and the crosslinking of polymeric ionic liquids, a recent sub-class of polyelectrolytes presenting ionic liquid-like centers on their polymer backbone and ionic liquid-like counter-ions remaining mobile in the dry state thanks to their highly dissociated nature. They will be made ideally (i) safe for skin contact by choosing bio-friendly ions and (ii) hydrophobic to enable the washability of the targeted textile. In a second step, he/she will investigate the coating of these ionoelastomers on highly electronically conducting CNT yarns that can be coiled to enhance their electromechanical response. The fabrication of CNT yarns by dry spinning of long and dense CNT forest produced by Chemical Vapor Deposition (CVD) process 2 will be investigated and optimized during a 6 months visit at CEA Saclay (near Paris). The influence of the coiling state of the yarns as well as the nature of the ionoelastomer coatings on the electromechanical response will be investigated to enhance their linear contraction and their response speed. The integration of the ionoelastomer/CNT actuating yarns into knitted and woven textile constructions will be finally investigated during a 2 months visit at the University of Borås (Sweden) and a demonstrator will be produced during a 1 month visit at Elitac company (Germany).
