Abstract:
The present invention provides a hybrid solgel modified electrode. It is a non-enzymatic biosensors that targets bio-molecules present in body fluids. The electrode comprises a base substrate [20] in the form of a bowl and a screen printed conductor [22] layer in the substrate. A hybrid solgel composite [24] is layered to cover the conductor [22] and substrate [20] layer, which is sensitive to body analytes by selective voltammetric oxidation of the bio-molecules. The hybrid solgel composite layer comprises tetraethylorthosilicate (TEOS), methyltriethoxysilane, phenyltriethoxysilane, carbon material, and ferrocene compounds (26, 28]. A method to fabricate the composite layer is also described. The typical analytes considered among the most important for medical diagnosis by analysis of blood, urine and sweat includes glucose, cholesterol, uric acid, creatine, urea and lactate. This electrode can be used in routine medical screening for both sick and healthy people.
Abstract:
The present invention provides an piezoelectric based energy harvester apparatus [20] consisting of a specially designed mechanical structure, hollow cylindrical structure [30] with a piezoelectric cantilever bridge [34] within its chamber, that upon exposure to the collected rain water incoming from the roof structure [24] into the post [26], will move or vibrate due to buoyant force of the strategically trapped rain water. With the structure built-in mechanical cantilevers bridge [34] that has piezoelectric properties, the vibration of the cylindrical structure [30] is followed by the generation of micro energy. Therefore, besides serving its traditional purpose for protection, post/pillar can also be used to produce energy which can power up low power electronic devices such as for precision agriculture application. This apparatus can also act as an alternative energy harvester during raining season where no sunlight is available. Fig. 2
