Article
The development of flexible and soft robots generates new needs in terms of instrumentation, as large encountered deformations require highly stretchable strain sensors. In this regard, we contribute to the adoption of inductive sensors by providing tools to model and exploit them, and showing their relevance experimentally. First, strain estimatio...
Conference Paper
The modularity concept in manipulators relies on connecting multiple elementary structures to achieve more complex and functional systems [1]. It has promising advantages, such as affordability and higher robustness [2], and allows for better adaptability to changing needs, e.g. enlarging the system workspace. Thus, modularity is highly desired in...

Soft and continuum robots are transforming medical interventions thanks to their flexibility, miniaturization, and multidirectional movement abilities. Although flexibility enables reaching targets in unstructured and dynamic environments, it also creates challenges for control, especially due to interactions with the anatomy. Thus, in recent years...

Dielectric elastomer generator (DEG) employs a soft capacitive transducer. This transducer is mainly used to convert ambient mechanical motion into electricity. The amplitude of the converted electrical signal is analogous to the magnitude of the mechanical motion. However, the inherently unpredictable nature of ambient mechanical motion causes ins...

With the emergence of different dielectric elastomer transducers, the characterizations of dielectric elastomers are essential aspects for the design purpose. In this work, two potential dielectric elastomers, acrylic-based VHB and silicone-based Ecoflex, are tested and characterized under common loading conditions called equibiaxial and biaxial lo...

In recent years significant attention has been made towards teleoperation of a humanoid robot using haptic devices. Methodologies developed are either cost prohibitive or they are not very effective. The lack of an effective, economical and a simple technique for teleoperation of humanoids is a barrier in exploring their full potential. In this pap...
Patent
The present invention provides a planar tensile testing device which is capable of testing mechanical properties of polymeric sheet material biaxially. The device is intended to test the mechanical properties of the elastomeric material in uniaxial, pure shear, equibiaxial and unequal biaxial modes of deformation. The device enables sliding of four...

The present disclosure provides an exoskeleton type energy harvester which is capable of converting mechanical energy of knee joint to useful electrical energy. The energy harvester consists of at least a dielectric elastomer transducer setup, an electrical charging circuit, a discharging circuit and an exoskeleton to be fitted at the knee joint us...
Patent
The present disclosure relates to a dielectric elastomer diaphragm based micro hydroelectric generator to convert hydraulic energy to electrical energy. This energy conversion device consists of at least a dielectric elastomer annular diaphragm transducer, a transmission mechanism, fixed frame and adjustable or movable frame. The dielectric elastom...
Conference Paper
