This paper proposed a novel prosthetic hand system integrated with a designed hybrid control method for achieving human-like grasping. The system design has been elaborated, including the mechanism design of a humanoid prosthetic hand equipped with multimodal sensing capabilities, a multi-channel EMG collector, a sensory feedback device, and a real-time central processing unit. A hybrid control method that combines electromyogram (EMG) and visual information was proposed to recognize the control intention of the system user. Preliminary verification of grasping experiments had been conducted, which proved the effectiveness of the prosthetic hand system and the hybrid control method. The development of this system aims to enhance the control performance and perceptual interaction capabilities of prosthetic hands while addressing limitations encountered in traditional myoelectric prosthetic hands. Besides, it could serve as a validation platform for assessing the control performance of diverse algorithms applied in practical applications.

A major barrier to the commercialization of pattern recognition (PR)-based myoelectric prostheses is the lack of robustness to confounding factors such as electrode shift which has been lingering for years. To overcome this challenge, a novel Duo-Stage Convolutional Neural Network (DS-CNN) is proposed. The DS-CNN is comprised of two cascaded stages in which the first stage deciphers the occurrence of a particular kind of shift upon which a requisite CNN model is triggered in the second stage for accurate decoding of individual motion intent, which is necessary for initiating robust control of the prostheses. The proposed scheme works on raw EMG signals as input which reduces the preprocessing time that would be required in conventional machine learning-based PR schemes, to effectively mitigate both transverse and longitudinal shifts using the same network architecture. This approach was validated for four distinct electrode shift conditions (with shifts in the range of 7.50mm-10.05mm) in a dataset obtained from 18 able-bodied subjects that performed 8 classes of targeted hand gestures. The experimental results show that the proposed dual-stage driven deep neural network model can adequately resolve the effects of electrode shift with classification accuracy near the No-shift scenario ( © 2023 IEEE.

Rehabilitation robots play an important role in the motor function rehabilitation for stroke survivors with hemiplegia. However, the rehabilitation effect of current robots is still limited partly because a single training of motor function can be strongly affected by the decreased blood supply function of the bedridden patients. This work proposed an approach to study the coupling relationship between the motor and blood supply functions by combining the synchronously recorded EEG and cerebral blood oxygen information, where the cerebrations in different movement paradigms were analyzed from an aspect of "functional coupling". The results show that the information of oxyhemoglobin concentration change (ΔHbO) can effectively indicate the cortex activation, and a stronger blood supply is needed in cortexes to perform body movements. The correlations within motor cortexes are significantly stronger than the ones between motor and prefrontal cortexes, and a higher resistance level of extremity training will cause stronger correlations. Calculation of transfer entropy (TE) shows that there exists a bidirectional information transmission between the electrophysiological and blood supply signals, and more information is transmitted always in the direction from ΔHbO to EEG than in the opposite direction. The information transmission or the coupling relationship can be significantly enhanced by extremity movements, and large TE values are achieved in the Theta, Beta and Gamma frequency bands of EEG that correspond to motor functions. This work has demonstrated the functional coupling between nerve and blood microcirculation, which would provide a technical guidance to improve the rehabilitation effect for current robot systems and have great application potentials. © 2023 IEEE.

Cerebral palsy (CP) is characterized by neuromotor disorders. It remains a huge challenge for ultra-early screening of CP. So far, the diagnosis of CP is mainly based on a combination of neuromotor assessment methods, magnetic resonance imaging (MRI) and clinical history. However, subjective errors are highly likely to be introduced in the process of CP screening due to disparities in clinicians’ professional backgrounds, working abilities and academic levels. Cutting-edge sensing techniques have been unveiled in the field of ultra-early CP prediction which provides objective diagnosis with quantified output information by obtaining motion capture, classification, and recognition. It is necessary to contrast the strengths, weaknesses, and potential of these techniques and how to apply them in the ultra-early screening of CP. This study compares and analyzes the latest and advanced sensing methods and discusses their future applications in infantile CP screening. The work could provide technical suggestions and clinical guidance for early intervention in the field of ultra-early CP screening later on.

Flexible photonic devices based on metasurfaces exhibit characteristics such as ultra-thinness and light weight, enabling versatile applications across various surfaces, particularly in smart wearable devices, visible light communication, and conformal optics, etc. Among existing methods, direct flip transfer and stamp-assisted transfer are the two most prevalent processes. However, metasurfaces produced by these methods are typically embedded within a flexible substrate, constraining the dielectric environment of the metasurface. Moreover, conventional approaches often utilize materials like metal or amorphous silicon for nanoantennas, leading to unnecessary optical losses. In contrast, monocrystalline silicon offers a larger scattering cross-section and lower absorption loss, promising superior performance for photonic devices[1-5]. Herein, we propose a method for fabricating reconfigurable, flexible centimeter-scale monocrystalline silicon metasurfaces. The process involves a polymer membrane containing monocrystalline silicon metasurface, followed by transferring the polymer onto a stretchable substrate (PDMS) utilizing water tension. The monocrystalline silicon nanoparticle arrays are affixed to the PDMS substrate via van der Waals force, with the surrounding area directly exposed to air. Further, photonic devices with upper and lower refractive index matching can be achieved by pouring PDMS. By adjusting the mechanical stretching of the photonic device, dynamic control of the light field can be realized. © 2024 SPIE.

The scoliosis with a prevalence of about 2.4% has become the top 3 major 'killer' of children and adolescents' health. Only 0.02% of scoliosis would be severe enough to require surgical intervention, while the rest was treated with orthotics or exercise training. However, the location of the orthotic forces and its effects were still not clear, resulting in a great deal of blindness in the fabrication of precise individualized orthoses and the later applied orthopedic forces. In this paper, we built a 3D spine model of a patient with idiopathic scoliosis based on CT tomography data, applied different orthopedic forces to the spine model to compare the results and clarify the relationship between them in order to determine the optimal location and magnitude of the orthopedic force, which were necessary for precise interventions in patients. The present results showed that 1) the greater the applied force, the better the correction effect (within reasonable limits) and 2) the effect of multiple forces applied for correction was better than that of a single force applied, as reflected by a greater displacement of the vertebrae and almost identical mean Von Mises stress in the discs, which could support the production of effective personalized orthopedic robots. © 2022 IEEE.
