A Love wave sensor with a phononic parylene-C wave guiding layer is proposed to detect the VEGF secreted during the selective platelet activation process, where arrays of a different material (filling material) are fabricated in the parylene-C films. The effects of the structural design parameters (period width and period number) on the electric response of sensors are investigated. As the period...
In this paper a dipole-type RFID tag antenna is proposed and it can be used to detect the mechanical deformation of an object. When the tag antenna is attached to an object, the mechanical deformation of the object and the patch antenna will contribute to the frequency deviation. So we can research and test the impact of mechanical deformation of the RFID tag antenna on its resonant frequency to monitor...
In this paper, a LCC series-parallel resonant converter is designed for the electromagnetic launch system, in which, the power supply charges for the energy-storage capacitor in the Pulse Forming Unit. At first, the operational principles of the LCC resonant topology operating in Discontinuous-Current-Mode are analized and the detailed expressions describing the resonant topology are derived. In order...
Some of intriguing advantages of Rogowski coils, such as high bandwidth, capability of measuring large currents, non-saturation and potential-free, make it possible to detect and diagnose large pulsed current from an electromagnetic launch system. In this paper, high frequency behavior for a Rogowski coil is analyzed. Considering the model of the coil frequency response, a design method for the transducer...
In injection-locked lasers, the phase-amplitude coupling cannot be characterized by the FM-to-AM ratio. The former exhibits a resonance due to the injected field and the equivalent α-factor can be larger than that of solitary laser.
Platelet-rich plasma (PRP) has been applied in a series of clinical treatments. PRP contains high-concentrated platelets, which, when activated, could secret a variety of growth factors and cytokines, to promote and/or enhance healing of injured tissues. Non-activated platelets suspension could be prepared by an isolation method of centrifugation and washing currently. However, it is not clear whether...
Impacts of gain compression on modulation properties of quantum dot lasers are investigated with a new modulation transfer function derived from a semi-analytical approach. Results show that non-linear gain causes severe degradations in laser dynamics.
Here we present a new microfabricated optical endoscope using a fully integrated optical waveguide with a push-pull piezoelectric actuator design. This new scanning probe was constructed using SU-8 epoxy-based photoresist as a resonant cantilever. The scanner was driven with a frequency of 25 Hz in the horizontal direction and a frequency of 4.71 kHz in the vertical direction. The best resolution...
Energy harvesting device which scavenges energy from the ambient and powers micro systems is receiving more and more attentions. In this paper, a linear generator for vibration energy harvesting is designed and fabricated. Volume of the generator core is 60.8 cm3, the mass of the device is 338 g, and the designed resonance frequency is 41 Hz. The vibration energy from an ordinary air compressor is...
