a carbon paste electrode modified with cobalt (ii) phthalocyanine (copc) was used as a sensitive potentiometric sensor for determination of ascorbic acid in aqueous solutions. the potential response of the electrode is a linear function of ascorbic acid concentration over the range 5 10 to 10 m (?1- 1800 µg ml ) with a nernstian slope of 56 mv at ph 7. the limit of detection was 0.2 µg ml ascor...

High-density sensor arrays were prepared with microbead vapor sensors to explore and compare the information coded in sensor response profiles following odor stimulus. The coded information in the sensor-odor response profiles, which is used for odor discrimination purposes, was extracted from the microsensor arrays via two different approaches. In the first approach, the responses from individ...

an extended octagonal ring (eor) transducer was designed and developed to measure forces inside the compression chamber of a large square baler in different directions. the transducer was calibrated by applying forces in three directions simultaneously and independently. the sensor revealed excellent linearity along with small cross sensitivities. horizontal and vertical primary sensitivities o...

Garment-integrated sensors equip clothes with a smart sensing capability, while preserving the comfort of the user. However, this benefit can be to the detriment of sensing accuracy due to the unpredictability of garment movement (which affects sensor positioning) and textile folds (which can affect sensor orientation). However, sensors integrated directly into garments or fabric structures can...
