This study aims to improve the torque performance and manufacturability of axial-flux permanent magnet (AFPM) machines. Hence, we propose a novel AFPM machine that employs a soft magnetic composite (SMC) core with tooth-tips constructed by a one-pres

The adoption of prosthetic hands by children with congenital upper limb deficiency from a very early age has benefits in terms of reducing prosthesis abandonment, improving body image, and mitigating developmental and physiological complications that

Iron-based sintered alloy materials have a problem with fatigue strength because the number of pores contained in the material is 10% by volume. Therefore, sintered materials are not applicable to gears used under high speed and high load, such as tr

Sintered materials are superior in productivity because of their simple process, but they are not applied to high-load gears because of their insufficient strength. To improve the fatigue strength of sintered materials, the authors have developed liq

We hypothesized that a single-leg version of the Hybrid Assistive Limb (HAL) system could improve the gait and physical function of patients with hemiparesis following a stroke. In this pilot study, we therefore compared the efficacy of HAL-based gai

Sintered materials are superior in productivity because of their simple process, but their mechanical properties are low. To improve the mechanical properties of sintered materials, we focus on liquid-phase sintering. In this study, we selected boron

Cerebral palsy (CP) patients with spastic diplegia struggle to perform activities of daily life (ADL) using their upper arms. The single-joint-type Hybrid Assistive limb (HAL) for upper limbs is a new portable robot that can provide elbow motion supp

We report a case in which elbow flexion exercises using the upper limb single-joint Hybrid Assistive Limb (upper limb HAL-SJ) were implemented in a patient 13 months postoperatively following elbow flexion reconstruction with intercostal nerve transf

Hemiparetic gait is a common condition after stroke which alters importantly the quality of life of stroke survivors. In recent years, several robotic interventions have been developed to support and enhance rehabilitation strategies for such populat

We developed Fe/FeSiAl soft magnetic powder cores (SMCs) for realizing the miniaturization and high efficiency of an electromagnetic conversion coil in the high-frequency range (∼20 kHz). We found that Fe/FeSiAl SMCs can be formed with a higher den
