Gait dynamics sensing using IMU sensor array system

The article deals with a progressive approach in gait sensing. It is incorporated by IMU (Inertia Measurement Unit) complex sensors whose field of acting is mainly the motion sensing in medicine, automotive and other industry, self-balancing systems, etc. They allow acquiring the position and orientation of an object in 3D space. Using several IMU units the sensing array for gait dynamics was made. Based on human gait analysis the 7-sensor array was designed to build a gait motion dynamics sensing system with the possibility of graphical interpretation of data from the sensing modules in real-time graphical application interface under the LabVIEW platform. The results of analyses can serve as the information for medical diagnostic purposes. The main control part of the system is microcontroller, whose function is to control the data collection and flow, provide the communication and power management

Sensor Array for Evaluation of Gait Cycle

The gait motion is an essential part of the life of every human being. The evaluation of human motion is a subject of complex approach and knowledge in the biomechanics area with application in orthopedics, therapy and commercial sporting applications. The monitoring and diagnostics allow determining the background of motion individualities and the defects reasons and impacts. The article describes the possibilities of gait cycle sensing, which has the potential for use in medical diagnostics and rehabilitation process monitoring. The system incorporates a matrix of four FSR (Force Sensing Resistor) pressure sensors and an accelerometric unit for the possibility of posture and step cycle evaluation so that it can be utilizable at diagnostic or rehabilitation during gait cycle retraining or sporting activities monitorin

VISUALIZATION OF MEMS STRUCTURES FOR EDUCATION OF AUTOMOBILE MICROSYSTEMS

The work is aimed at visualization of working principles of microelectromechanical sensors which are used in automobile electronic systems. Attention is paid to accelerometric, inclinometric, pressure and MAF devices. These are used in systems for stability control, passive and active safety as well as comfort management. The visualizations were realized using modern animation techniques initiated by the creation of virtual materials, 2D and 3D objects, through scene exposure, pending their animation and final cutting

ANISOTROPIC CONDUCTIVE JOINTS UTILIZATION FOR JOINING OF FLEXIBLE CABLES AT RIGID SUBSTRATES

Key motivation of this work is the industrial task of standard lead based solders joints elimination in electronics, which comes out from the European Council requirement to exclude lead from the soldering process before the middle of 2006. The main emphasis was laid on the new approaches in tasks solving by using standard electrotechnologies and available production facilities. Results of this work were based on two types of anisotropic interconnections usability as an alternative of soldered joints in the production process, which is generally used for a reflow of the standard SnPb solder between the contact areas. Practical results of the performed study indicate that realized joints with applied anisotropic conductive adhesive have comparable electrical resistance with soldered interconnections. The lower mechanical strength is less relevant with concerning of operating conditions. The anisotropic conductive paste application demonstrates their suitability for copper-to-gold plated contacts conductive joining; however, adhesive joints realized by an anisotropic conductive tape were not satisfactory

Advanced Prototype of Manus Diagnostics and Rehabilitation Device

Hand fine motor functions may be impaired by various conditions, from injury to neurodegenerative diseases. Previously, we developed a prototype called Rehapiano that used load cells to measure the force exerted by the individual fingers. Rehapiano could distinguish between Parkinson’s patients and healthy individuals by analysing the finger tremors. Based on the experiences with the prototype and consultations with experts, we developed a more advanced prototype, Rehabimano. We show here how we improved the ergonomics and electronics. In addition, we have performed experimental validation of the device and confirmed its ability to detect and measure frequencies of tremors. These results are a stepping stone for consecutive software development and pre-clinical trials
