A Comparative Characterization of Smart Textile Pressure Sensors.

This research study investigates the impact of various insulating textile materials on the performance of smart textile pressure sensors made of conductive threads and piezo resistive material. We designed four sets of identical textile-based pressure sensors each of them integrating a different insulating textile substrate material. Each of these sensors underwent a series of tests that linearly increased and decreased a uniform pressure perpendicular to the surface of the sensors. The controlled change of the integration layer altered the characteristics of the pressure sensors including both the sensitivity and pressure ranges. Our experiments highlighted that the manufacturing design technique of textile material has a significant impact on the sensor; with evidence of reproducibility values directly relating to fabric dimensional stability and elasticity.

A qualitative evaluation of information leaflets for gastroscopy procedure.

Written information sent to patients prior to diagnostic gastroscopy is an important part of the process of informing and preparing them for the procedure. Yet there is ample evidence in the literature that information leaflets do not measure up to the required standard. In this study, information leaflets from a random sample of seven hospitals in Northern Ireland that carried out gastroscopy as a day procedure were evaluated using a checklist of items recommended by the British Society of Gastroenterology (BSG) for inclusion in leaflets for patients undergoing diagnostic gastroscopy. The results showed that the number of written materials sent to patients prior to the procedure varied between units. There were inconsistencies in the information given by the same unit, and overall, there was a lack of vital information in most of the leaflets. Some of the information was confusing and ambiguous. The potential risk of the procedure was explained in only one of the leaflets. Patients' right to choose to have a mild sedative was not made clear in most of the leaflets. More should be done to address these gaps and inconsistencies in the written information provided to patients prior to gastroscopy.
