Diabetic individuals need simple, accurate, and cost effective means by which to independently assess their glucose levels in a non-invasive way. In this work, sensor based on randomly oriented CuO nanowire networks supported polyethylene terephthalate thin film is evaluated as flexible, transparent, non-enzymatic sensing system analogous those envisioned for future wearable diagnostic devices. The amperometric characteristics of type device architecture are both before after bending, with...
Over the past decade, there has been special interest in developing nonlinear energy harvesters capable of operating over a wideband frequency spectrum. Chief among harvesting techniques is magnetic levitation–based harvesting. Nonetheless, current approaches encapsulate design challenges. This work investigates some issues and limitations faced by traditional such as damping schemes stiffness nonlinearities. Both experiment model are used to quantify evaluate regimes nonlinearities present...
In this work, development of a broadband nonlinear electromagnetic energy harvester is described. The consists casing housing stationary magnets, levitated magnet, oblique mechanical springs, and coil. Magnetic springs introduce behavior into the harvester. A mathematical model proposed device developed validated. results show good agreement between experiment. significance adding to design investigated using simulation. from suggest that will improve performance increase frequency bandwidth...
In this work, a unique magneto-mechanical energy harvester is fabricated, modeled, and investigated. The magnetomechanical consists of levitated magnet, forming magnetic spring, connected to oblique, mechanical springs. Upon base-excitation, the magnet experiences nonlinear forces in direction motion due spring. Voltage induced coil placed around body harvester. Results confirm springs introduce geometric negative hardening stiffnesses. This behavior allows for use disc magnets instead ring...
