Disposable cartridge biosensor platform for portable diagnostics
(SPIE , 2017)We developed two types of cantilever-based biosensors for portable diagnostics applications. One sensor is based on MEMS cantilever chip mounted in a microfluidic channel and the other sensor is based on a movable optical ... -
Graphene as a piezoresistive material in strain sensing applications
(MDPI, 2022-01-12)High accuracy measurement of mechanical strain is critical and broadly practiced in several application areas including structural health monitoring, industrial process control, manufacturing, avionics and the automotive ... -
Identification and evaluation of cracks in electrostatically actuated resonant gas sensors using Harris Hawk / Nelder Mead and perturbation methods
(Techno-Press, 2021-01)In this paper we study the static deflection, natural frequency, primary resonance of an electrostatically actuated cracked gas sensor. Besides, a novel hybrid metaheuristic algorithm is proposed to detect the location and ... -
Low-loss optical switch using Brewster angle
(IEEE, 2011)Fabrication and actuation errors of submicron silicon waveguide optical switches are reported to remain within sub-100 nm ranges. These errors cause high loss ruining the optical performance of the switches at the on-state. ... -
Microcantilever based LoC system for coagulation measurements
(Chemical and Biological Microsystems Society, 2014)In this paper, a microcantilever-based system enabling multiple coagulation tests on the same disposable cartridge is demonstrated. The system consists of independent cartridge and reader unit. The actuation of the nickel ... -
Two cantilever based sytem for viscosity and density monitoring
(IEEE, 2015)Viscosity and density measurements in liquids in real-time is challenging. Previous MEMS based approaches use frequency sweeps for the purpose and those methods are slow and not real-time. We show that high precision ...
