A prosthetic hand with human-like grasping behavior outperforms what is required in the execution of activities daily living.
The simultaneous breaking of time-reversal and inversion symmetry can lead to peculiar effects in Josephson junctions, such as the anomalous effect or supercurrent rectification, which is a dissipationless analog diode effect. Due their impact new quantum technologies, it important find robust platforms external means manipulate above controlled way. Here, we theoretically consider junction based on spin Hall system normal channel, subjected magnetic field direction defined by spin-momentum...
For decades, powered exoskeletons have been considered for possible employment in rehabilitation and personal use. Yet, these devices are still far from addressing the needs of users. Here, we introduce TWIN, a novel modular lower limb exoskeleton use spinal-cord injury (SCI) subjects. This system was designed according to set user requirements (lightweight autonomous portability, quick donning setup, stability when standing/walking, cost effectiveness, long battery life, comfort, safety)...
A pressing challenge in the design of actuated knee prostheses is ability to address high variation speed and torque requirements for different types phases locomotion. This manuscript presents a novel over-actuated prosthesis which makes use dual motor actuation architecture this issue. It utilizes speed/low enable natural highly dynamical motion, as required swing walking, permanently engaged. In addition motor, clutchable uni-directional low dynamics present assist during execution tasks...
Literature highlights how trainings in virtual and augmented settings can contribute to a higher level of embodiment bionic prosthetic limbs. In this paper, Spatial Augmented Reality (SAR, where the augmentation real environment is based on displays surfaces instead being worn by user) system was used two conditions characterised absence or presence social feature that should improve user engagement. first condition, subject has contract quadriceps right leg command, through EMG sensors,...
Literature highlights how virtual and augmented settings offer engaging solutions to improve one's feeling of an artificial limb embodiment. In this paper, we explored the potential a setting for Spatial Augmented Reality (SAR, where display augments surface without making user wear any visor) in two conditions lower ownership training involving subjects disabilities. first condition, subject must contract quadriceps leg commanding (through electromyography, EMG) (a 3D model Hybrid Knee...
The paper presents a novel, semi-active, bionic knee design for transfemoral amputees. research exploits linear electro-hydrostatic actuation (EHA) unit, in series with flow control hydraulic valve, to assist deambulation tasks. High torque, low speed tasks are managed by the valve. Conversely, EHA is exploited torque tasks, either or regeneration mode. Traditional bio-mechanical requirements discussed and revised propose human-centered design. Specifically, focus towards amputees comfort...
Clock-spin models are attracting great interest, due to both their rich phase diagram and connection parafermions. In this context, we derive an exact local mapping from clock-spin fermionic partition functions. Such mapping, akin techniques introduced by Fedotov Popov for spin $\frac{1}{2}$ chains, grants access well established numerical tools the perturbative treatment of systems in framework. Moreover, one dimension, it allows use bosonization low energy properties models. Finally, aside...

Recent human-centred design studies suggest that acoustic noise could affect the physical use and psychological acceptance of a biomedical device. These aspects are especially relevant in prosthetic field, which device loudness is often related to rejection. The aim study inquire on possibility reduce emitted by robotic leg prosthesis improving its casing. First, emissions characterized experimentally using an anechoic chamber, both for whole prosthesis, actuator (i.e., source) isolation....
We study the role of edges in determining features topological phase a quasicrystalline higher order insulator. consider specific model consisting two stacked Haldane models with opposite Chern number and $30^\circ$ twist, whose structure is crystallographically equivalent to that graphene quasicrystal. find gap-opening low energy spectrum insulator occurs at different energies when kinds are considered. Crucially, bearded bonds appear be necessary for gap close charge neutrality point. In...
The experimental realization of twisted bilayer graphene strongly pushed the inspection systems. In this context, it was recently shown that a two layer Haldane model with thirty degree rotation angle between layers represents higher order topological insulator, zero-dimensional states isolated in energy and localized at physical vertices nanostructure. We show, within numerical tight binding approach, zero dimensional depends on geometrical structure vertices. most extreme cases, once...
