The importance of understanding the mechanical behavior of tissues is starting to be recognized in medical diagnostics. It is becoming clear that pathological tissues behave mechanically differently than do healthy tissues. However, traditional optical evaluation methods, particularly speckle-based methods, have not proven to be effective in assessing the mechanics of biological soft tissues. T...

In order to monitor pressure under feet, this study presents a biomechanical model of the human foot. The main elements of the foot that induce the plantar pressure distribution are described. Then the link between the forces applied at the ankle and the distribution of the plantar pressure is established. Assumptions are made by defining the concepts of a 3D internal foot shape, which can be e...

Three-dimensional (3D) printing has a variety of applications, from efficient iterations of engineering designs to fabrication of tissues for regenerative medicine. In soft robotics, 3D-printed functional materials can be used to mimic biological functions. Soft robotics overcomes some of the limitations of traditional rigid-body robotics through the ability to conform to different shapes and t...

Implementing the dynamic resources sharing is the radical objective of a Grid system. Because resources from Grid are wide-area distributed, heterogeneous and temporary, how to organize and manage such resources is a challenge. For addressing these problems, we introduce soft-sensors to monitor the resources changes, and propose a scenario for sharing the dynamic resources based on the monitori...

There exists a need within the Department of Defense (DoD) to provide a highly responsive and costeffective anomaly detection capability for satellite health monitoring. The solution must address current Battle Management Command and Control (BMC2) deficiencies. A soft-computing solution is robust in that it could be engineered to detect anomalies without requiring pre-set thresholds and thus e...

Measurements of temperatures and flows and pressures are used to estimate the dry point of the product for the distillation column. The Problem is characterized by the model complication and the strong colinearity between the measurements. In this article, the distributed RBF neural network (DRBFN) and principal component analysis (PCA) are used to develop the soft sensor (PCA-DRBFN model), and...

In conventional wastewater treatment one of the main problems confronting the plant manager is the estimation of the organic carbon removal efficiency, from which a mass balance can be computed. This paper presents a simple, albeit approximate, solution to this problem via a soft sensor approach. The basic idea is to apply a set-point control to the dissolved oxygen in the aerated compartment, ...

We propose a new method of tactile sensing for a fingertip of robotic hand. Using a simple fingertip with soft surface cover and a six-axis force/moment sensor, developed is a new function of measuring direction of edge when the fingertip contacts with an edge of the object. The developed function is useful not only to plan strategies for stable grasp and dexterous manipulation but also to reco...

A soft contact-lens amperometric glucose sensor as novel wearable device of body sensor network was fabricated and tested. Also, the sensor was utilized to tear glucose monitoring. The sensor was constructed by immobilizing GOD onto a flexible oxygen electrode, which was fabricated using “Soft-MEMS” techniques onto a functional polymer membrane. In purpose of bioinstrumentation, adhesive agents...

The practical utilization of soft nanocomposites as a strain mapping sensor in tactile sensors and artificial skins requires robustness for various contact conditions as well as low-cost fabrication process for large three dimensional surfaces. In this work, we propose a multi-point and multi-directional strain mapping sensor based on multiwall carbon nanotube (MWCNT)-silicone elastomer nanocom...
