Pressure Measurement System

The article presents the negative aspects of the influence of static and dynamic acceleration on the accuracy of pressure measurement for a selected type of transmitter. The influence of static accelerations from catalog notes was shown and compared with the tests results for a few selected sensors. The results of research on the influence of dynamic acceleration for various types of its variability for selected converters are presented. Moreover, a method of measurement patented by the authors that uses a complex transducer is shown. The method allows for more accurate measurements on moving objects. The tests were performed based on the proposed method. The obtained results of the influence of acceleration on the classical sensor as well as the construction using the proposed method are shown. The paper presents approximate pressure measurement errors resulting from the influence of acceleration. For example, errors in measuring the speed of an airplane may occur without the proposed method. The last part of the article presents a unique design dedicated to a multi-point pressure measurement system, which uses the presented method of eliminating the influence of accelerations on the pressure measurement.

Pressure Measurement System

In this work an effective MEMS based capacitive pressure measurement system is proposed. Thepressure sensing element consists of two capacitorplates. Thebottom plate is mechanically fixed, whilethe upper plate is a flexible silicon membrane with flexures. The pressure acts on the upper plate. Avariable separation between the plates is introduced.Maximizing the deflection of the plate is a keyto improve the sensitivity of the sensor. In this paper various flexure designs are studied. A comparison of the flexure sensitivity is made for the automobile tire pressure range.

Pressure Measurement System

The accuracy and repeatability of both electronic pressure sensors and static-film sensors, when used for in situ pressure distribution testing has previously been performed for various joints. Although both methods are reported to yield reasonable levels of accuracy, our initial experiments did not yield such good results. In addition, our joint of interest, the radiocarpal joint, was different from those previously studied. To be certain of the maximum accuracy that could be expected from each measurement system, we devised a controlled experiment to determine the accuracy of both systems in an idealized test configuration. The purpose of this study was to compare the accuracy and variability of a static-film pressure measurement system and an electronic pressure measurement system. We hypothesized that the static-film pressure measurement system would be more accurate under ideal conditions, due to its higher resolution.

Neuropathic Ulcers

Few scientific data are available on the effectiveness of commonly used modalities for reducing pressure at the site of neuropathic ulcers in persons with diabetes mellitus. The authors' aim was to compare the effectiveness of total contact casts, half-shoes, rigid-soled postoperative shoes, accommodative dressings made of felt and polyethylene foam, and removable walking casts in reducing peak plantar foot pressures at the site of neuropathic ulcerations in diabetics. Using an in-shoe pressure-measurement system, data from 32 midgait steps were collected for each treatment. There was a consistent pattern in the devices' effectiveness in reducing foot pressures at ulcer sites under the great toe and ball of the foot. Removable walking casts were as effective as or more effective than total contact casts. Half-shoes were consistently the third most effective modality, followed by accommodative dressings and rigid-soled postoperative shoes.
