On the design of a triaxial accelerometer

A Simple and Fast Method for Field Calibration of Triaxial Gyroscope by using Accelerometer

Design, realization and characterization of a symmetrical triaxial capacitive accelerometer for medical applications

Small triaxial accelerometc~a are needed in the medical field fl~r the monitoring of mobility. For this purpose, a new highly symmetrical inherently tri a'dal capacitive accelerometer has been designed. The basic structure of the dex ice consists of six capacitors surrounding a central n,.a:~ which is suspended by springs made of the rubber elastic polymer polydimethylsiloxane. The advantages o...

Design and fabrication of three axes accelerometer

Technology can provide safety in physical practices and improving the performance of these activities, so manufacturing of equipments for these purposes has been considered widely. The aim of the present paper was design and fabrication of three-axis accelerometer. hree acceleration sensors, three gyroscopes for angular velocity measurement, a microcontroller for converting analog data to ...

The validity of the non-exercise activity thermogenesis questionnaire evaluated by objectively measured daily physical activity by the triaxial accelerometer

BACKGROUND Physical inactivity is a major cardiovascular risk factor. Recently, we showed that non-exercise activity thermogenesis (NEAT) assessed by the self-reported questionnaire is favorably associated with metabolic risks in patients with type 2 diabetes. The purpose of the present study was to examine the validity of the questionnaire by comparing with objectively measured daily physical ...
