The Reliability of Polyvinylidene Fluoride Sensor for Intra- and Intersession Measurements.

A new nasal sensor has been designed using Polyvinylidene fluoride (PVDF) film using its piezoelectric property to measure nasal patency. The aim of this study is to determine the intra- and intersession reliability of the new PVDF nasal sensor measurement of unilateral and combined nasal parameters in a group of healthy subjects. Two identical nasal sensors: for right nostril (RN) and left nostril (LN) were designed using piezoelectric natured PVDF films.

Iontophoretic delivery of lidocaine hydrochloride through human skin.

Iontophoresis is one of the widely used noninvasive and painless transdermal drug delivery technique. Transdermal delivery of Lidocaine Hydrochloride using continuous and modulated iontophoresis were evaluated across human skin and further assessed for skin tolerance in the Swiss albino mice. Continuous DC was modified into modulated DC by introducing ON-OFF time in continuous DC.

Effective permeation of 2.5 and 5% lidocaine hydrochloride in human skin using iontophoresis technique.

Background: Lidocaine Hydrochloride (HCL) is one of the commonest topical local anesthetic drugs. The permeation of the lidocaine can be enhanced by iontophoresis (IOP). The purpose of this study was to evaluate the permeability of 2.

Evaluation of polyvinylidene fluoride nasal sensor to assess deviated nasal septum in comparision with peak nasal inspiratory flow measurements.

Background: Deviated nasal septum (DNS) is one of the major causes of nasal obstruction. Polyvinylidene fluoride (PVDF) nasal sensor is the new technique developed to assess the nasal obstruction caused by DNS. This study evaluates the PVDF nasal sensor measurements in comparison with PEAK nasal inspiratory flow (PNIF) measurements and visual analog scale (VAS) of nasal obstruction.

Piezoelectric sensing: Evaluation for clinical investigation of deviated nasal septum.

Noninvasive objective evaluation of nasal airflow is one of the important clinical aspects. The developed polyvinylidene fluoride (PVDF) sensor enables measurement of airflow through each side of the nose using its piezoelectric property. This study was designed to evaluate the diagnostic capability of the PVDF sensor in assessing the deviated nasal septum (DNS).
