Stimuli-induced bi-directional hydrogel unimorph actuators
Stimuli responsive hydrogels may be promising materials for shape transforming structures due to their ability to deform significantly in response to an environmental stimulus without the need for external power. It is well-known that by laminating swelling hydrogels and non-swelling flexible materials, such as inert elastomers, bending actuation can be achieved. In this work, we report an impr...
متن کاملNonlinear Hamiltonian modelling of magnetic shape memory alloy based actuators
This paper proposes an application of the Lagrangian formalism and its Hamiltonian extension to design, model and control a mechatronic system using Magnetic Shape Memory Alloys. In this aim, an original dynamical modelling of a Magnetic Shape Memory Alloy based actuator is presented. Energy-based techniques are used to obtain a coherent modelling of the magnetical, mechanical and thermodynamic...
متن کاملDesigning lead-free antiferroelectrics for energy storage
Dielectric capacitors, although presenting faster charging/discharging rates and better stability compared with supercapacitors or batteries, are limited in applications due to their low energy density. Antiferroelectric (AFE) compounds, however, show great promise due to their atypical polarization-versus-electric field curves. Here we report our first-principles-based theoretical predictions ...
متن کاملMagnetic Shape Memory Actuators for Fluidic Applications
Magnetic Shape Memory (MSM) actuators represent a new type of smart electromagnetic actuators where the MSM material elongates and contracts in a magnetic field. The MSM material has the ability to change its size or shape very fast and many million times repeatedly. Based on internally designed and produced Magnetic Shape Memory materials, the ETO GROUP has developed its new MAGNETOSHAPE® tech...
متن کاملShape memory alloy actuators and their reliability
We have developed two types of shape memory alloy (SMA) actuator and estimated the long-term reliability of SMA microcoils. A tube type tip articulator consists of 4 sets of SMA microcoil (wire diameter: 0.125 mm, coil diameter: 0.5 mm) for driving source and super elastic alloy (SEA) microcoils (wire diameter: 0.1 mm, coil diameter: 0.5 mm) for bias springs, support plates and flexible outer t...
