The next generation of implantable medical devices focuses on minimally invasive miniaturized solutions that operate reliably at large depths, provide duplex communication for closed-loop therapies, and enable multi-access for a network of implants to gather information or provide systemic interventions. Using ultrasound (US), power and data can be efficiently transferred through the body as its wavelength...
This paper presents a digital closed loop control method for the sense mode of a mode-matching MEMS vibratory gyroscope. The sense closed loop system reported in our previous work is relatively complex and unreliable due to the existence of notch filter. In this work, a more simple and robust control system is realized with the help of mode-matching control. With a tuning voltage automatically applied...
This paper presents a novel array of four film bulk acoustic resonators (FBAR) having four distinct fundamental resonant frequencies that offers parallel and/or combinatory mass sensing of multiple chembio species, such as various proteins. To achieve the multiple resonant frequencies, we connect multiple FBARs (having slightly different resonant frequencies, thus each representing a unique sensor)...
This paper proposes a linearised state-space technique to accelerate the simulation of tunable vibration energy harvesting systems by at least two orders of magnitude. The paper provides evidence that currently available simulation tools are inadequate for simulating complete energy harvesting systems where prohibitive CPU times are encountered due to disparate time scales. In the proposed technique,...
This paper reports radiation effects on mechanical characteristics of MEMS fixed-fixed beams and cantilevers after Co60 radiation. Radiation test is performed and resonant frequencies are measured by LDV. And stress relaxation has been recognized as main reason by theoretical analysis.
We report surface-plasmon enhanced fluorescence in CdSe/ZnS semiconductor quantum dots via linear and nonlinear excitations. 2times and 10times fluorescence enhancements have been achieved for linear and nonlinear excitations, respectively.
