Quantitative evaluation concerning principal gait locomotion pattern of a trans-femoral amputee with a prosthetic limb based on the intersegmental coordination

Nihon Kikai Gakkai ronbunshu, 2015
In human gait locomotion analysis, which is one useful method for efficient physical rehabilitation to define various quantitative evaluation indices, ground reaction force, joint angle and joint loads are measured during gait.

Joint angle measurement by stretchable strain sensor

Journal of Ambient Intelligence and Humanized Computing, 2018
Measurement of body motion is required in professional and amateur sports and in health-care services for the improvement and evaluation of human motion. This study proposes a method for measuring joint angles. The key device in this method is a stretchable strain sensor.

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning

Advanced Engineering Materials, EarlyView.
The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.

Gallium Microalloying in Bi–Sn Solders: Interfacial Phase Formation, Wettability, and Long‐Term Shear Reliability Under Isothermal Aging

Advanced Engineering Materials, EarlyView.
Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

Primary motor cortex neurons during individuated finger and wrist movements: correlation of spike firing rates with the motion of individual digits versus their principal components

Frontiers in Neurology, 2014
The joints of the hand provide 24 mechanical degrees of freedom. Yet 2 to 7 principal components (PCs) account for 80 to 95 % of the variance in hand joint motion during tasks that vary from grasping to finger spelling.

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

Advanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

A method for a categorized and probabilistic analysis of the surface electromyogram in dynamic contractions

Frontiers in Physiology, 2015
The human motor system permits a wide variety of complex movements. Thereby, the inter- individual variability as well as the biomechanical aspects of the performed movement itself contribute to the challenge of the interpretation of sEMG signals in ...
