Measurement of Surface Displacement Excited by Emat Transducer
− The article discusses the measurement of surface displacement of an electrically conductive solid material. Deflection is excited by electro-magneto-acoustic transducer (hereinafter referred to as EMAT). Measurement is realized by laser interferometer. In our research the precise surface displacement measurement is necessary for two reasons. First is EMAT transducer numerical model convergenc...
متن کاملThe Accelerometer Mmg Measurement Approach, in Monitoring the Muscular Fatigue
This research aimed to appreciate whether the mechanomyogram (MMG) may be used to monitor the muscle behavior under fatiguing exercise. The electromyogram (EMG) and MMG were simultaneously recorded from the Biceps and from the Brachioradialis muscles, with surface electrodes EMG, and accelerometer based transducers – MMG, from sixteen subjects. The conclusions are consistent in validating the u...
متن کاملA Linear, Millimetre Displacement-to-Frequency Transducer
The paper presents a novel linear, high-fidelity millimetre displacement-to-frequency transducer, based on the resistive conversion of displacement into a proportional voltage, and then frequency. The derivation of the nonlinearity, fidelity and sensitivity of the transducer is presented. Experimental results confirm that a displacement of 0-100 mm is converted into a frequency range of 0-100 k...
متن کاملUse of MMG signals for the control of powered orthotic devices: development of a rectus femoris measurement protocol.
A test protocol is defined for the purpose of measuring rectus femoris mechanomyographic (MMG) signals. The protocol is specified in terms of the following: measurement equipment, signal processing requirements, human postural requirements, test rig, sensor placement, sensor dermal fixation, and test procedure. Preliminary tests of the statistical nature of rectus femoris MMG signals were perfo...
متن کاملDevelopment of a Wireless Displacement Measurement System Using Acceleration Responses
Displacement measurements are useful information for various engineering applications such as structural health monitoring (SHM), earthquake engineering and system identification. Most existing displacement measurement methods are costly, labor-intensive, and have difficulties particularly when applying to full-scale civil structures because the methods require stationary reference points. Indi...
