This paper presents a power management system of self-supplied wireless sensor node based on MEMS electret vibrational energy harvester. The storage and control policy of the management circuit is optimized for small ambient excitation conditions to reduce power dissipation and avoid failure in wireless data transmissions. Live acceleration data collected from a bridge as well as simulation results were used to confirm the feasibility of the proposed circuit operating in real case low vibration environment.

This paper presents three novel techniques for the measurement of capacitance variation in high-frequency operation of angular comb-drive structures, with applications including optical projection micro-mirrors. The first technique uses a lock-in amplifier in order to measure the impedance of the comb structure by superimposing a test signal having a frequency that is at least one order of magnitude higher than the micro-mirror resonant frequency. The second measurement setup uses a digitizing oscilloscope to measure the capacitance from the instantaneous voltage and current in the comb structure. The third setup consists of a micro probe controlled by a high-resolution positioner in order to tilt the mirror to a desired angle. This allows for static capacitance measurement at different mirror deflection using a high precision LCR meter. The measurement results from the different setups were found to be in agreement with each other. The results were further verified against analytical and numerical modelling.

This work presents a method to fabricate the diamond nanowire at the tip of silver nano-grating which acted as the Plasmon substrates to enhance the quantum efficient of diamond NV color centers for the quantum sensors applications. Due to the well-organized silver nano-grating, the edges of colloidal diamond drop-casted on the silver nano-grating substrate have been arranged as the straightforward lines. And, the diamond nanowire would be manufactured along this line at the tip of silver nano-grating based on the coffee-ring effect. Because of the tip effect and the surface plasma resonance effect at the tip of silver nano-grating, the fluorescence and the quantum efficient have improved about 10 times. It was the potential methods to improve the sensitivity of spin-based sensors by improving the quantum efficient.

Advances in microfluidic research have allowed digital microfluidic (DMF) chips to be rapid prototyped using inexpensive materials and simple fabrication processes to the extend where the time spend on chip design can be significantly longer than the time required for fabrication. The growing need for application specific DMF chips challenges efficient handling of the increasing chip design and programming complexity. To address this, we propose a correct-by-construction modular chip design approach, which allows chips to be constructed from a component library and verified by simulation before fabrication. After fabrication, the chip is operated from a smartphone by remote instrumentation of a portable DMF chip control device. By combining structured design techniques with custom developed hardware and software tools, we present a full end-to-end solution for fast DMF chip design, simulation and operation.
