This paper presents a novel multimodal MEMS structure applied for piezoelectric energy harvester. The device consists of two meandering beams and four different length masses, which act as a spring-mass system. The meandering beams decrease operating frequency, adjust to lower ambient excitation. And the four different masses increase modes of the whole structure. More importantly, the Finite Element...
A fourier analysis applied to the Fabry-Perot interferometer(FPI) transmission spectrum for temperature measurement is proposed and experimentally demonstrated in this paper. In the fast Fourier transform (FFT) spectrum of the FPI transmission spectrum, a higher order model is separated from the transmission spectrum and the spatial frequency spectra of the higher order model is detected. As the temperature...
In proton exchange membrane electrolyzer cells (PEMECs), the oxygen generated at the anode side by electrochemical reactions is forced out of cells through the micro channels and liquid/gas diffusion layer, meanwhile, the water flows through the same pathways to reach the reaction sites in an opposite direction, during this process, the complex two-phase counter flow is formed. The two-phase transport...
A diagnostic system was setup to test the ferroelectric micro-plasma thruster(FMPT). The V-I characteristic of the FMPT was measured. The optical spectrum of microplasma generated in FMPT was obtained. Additionally, the electron temperature has been found to be ∼3.43 eV from atomic Boltzmann plots of neutral Ag I lines.
