Variable recruitment in bundles of miniature pneumatic artificial muscles.

Bioinspiration & biomimetics Sep 13, 2016
The natural compliance and force generation properties of pneumatic artificial muscles (PAMs) allow them to operate like human muscles in anthropomorphic robotic manipulators. Traditionally, manipulators use a single PAM or multiple PAMs actuated in ...

Calculation of upper esophageal sphincter restitution time from high resolution manometry data using machine learning.

Physiology & behavior Aug 10, 2016
OBJECTIVE: After swallowing, the upper esophageal sphincter (UES) needs a certain amount of time to return from maximum pressure to the resting condition. Disturbances of sphincter function not only during the swallowing process but also in this phas...

Improving the ground reaction force prediction accuracy using one-axis plantar pressure: Expansion of input variable for neural network.

Journal of biomechanics Jul 30, 2016
In this study, we describe a method to predict 6-axis ground reaction forces based solely on plantar pressure (PP) data obtained from insole type measurement devices free of space limitations. Because only vertical force is calculable from PP data, a...
