This paper discusses the behavior of MEMS gyroscopes during power supply fluctuations, which is a problem that has not been sufficiently analyzed to date. The focus is placed on the scale factor. In the opening section, the authors present the basic output configurations of the MEMS gyroscopes and propose their general models. The following part of the article has a practical character. Here, eight types of the above-defined gyroscopes are examined to demonstrate the influence of the applied supply voltage. Firstly, the measurement procedure is described, and subsequently the results of this experiment are presented. The outcome of the performed research consists in that the scale factor error is smaller than 1% if the power supply voltage fluctuates within the range of ±0.25 V around the nominal value.

The problem of detecting leakages in pipelines has been assuming a crucial importance for saving water from bad usage and exploitation. FDM (Filter Diagonalization Method) is a promising method used in nuclear magnetic resonance for decaying issues. We propose a comparison between a one-dimensional FDM and a multidimensional one. This comparison points out interesting aspects related to the leak width and noise contained in the signal and that are hidden in 1 D FDM. An interesting result is the fact that, thanks to multidimensional approach, finding other peaks and lobes, it is possible to improve the construction of a pipelines and to reduce the number of sensors to be located on the pipeline.

Little is currently known about the foraging behavior of free ranging animals, particularly in biodiverse pastures. This is despite the suggestion of recent work that animals grazing on such pastures tend to produce better quality meat. This paper presents a bespoke Wireless Sensor Network system designed to be mounted on grazing animals and collect movement information which is then coded with reference to human observations. In doing this it has been possible to calibrate the bespoke system such that, in realtime, the system can be used to deduce animal behavior (e.g. resting, grazing, foraging, etc.) remotely. When coupled with future GPS-free positional information, this system will provide valuable information for the UK agricultural industry, in addition to overcoming the challenges faced by many commercial systems which rely on energy intensive GPS technology.

This work reports on coalescence-induced self-propulsion as a driving mechanism to actuate microfluidic droplet assays. We demonstrate multi-droplet translation and assay-type sensing on a digital microfluidics platform by use of surface tension gradients alone. These gradients arise during the coalescence of two droplets of liquid having different compositions and therefore surface tensions. We demonstrate a chemi-luminescence blood-detection reaction based on the mixing of two carrier droplets containing solutions of synthetic blood and luminol sensor solution. Presence of iron in the blood solution is recorded using digital imaging and analyzed via offline image processing. The results demonstrate the capability of the propulsion mechanism to propel droplets over several millimeters, thus enabling one to design a new family of chip-based biochemical sensor assays.

In recent years, microphone array signal processing has been actively studied in the field of engineering. In consideration of our hope that children's interest in this technology will contribute to the future development of science and technology, we have developed the KIKIWAKE system with a microphone array and conducted the Prince Shotoku Game to promote children's interest. Then, we confirmed the effectiveness of the system through interviews.

A wireless radiation monitoring system has been developed using a sensor network and one board-type radiation module. The one board-type radiation module is based on the Pocket Geiger type5 by Radiation-watch.org[1]. The power consumption of the module was reduced to 3 mW to drive the monitoring system by a solar cell. The module is designed to connect a Gvove terminal of Arduino microprocessors. The radiation dose rate was transmitted by wireless modules (Xbee, RF bee, etc.), and collected by the application program. The communication distance of the module was around 40-160 m in a straight-line distance. A novel 920MHz module has been developed by combining the radiation module and a PIC32bit microprocessor. The communication distance by using the module is over 3 km in a straight-line. Software was designed to form a mesh network. Because a lower power radiation detector is required for environmental measurements around the Fukushima nuclear plant, a custom detection ASIC has been designed using a 0.6-μm CMOS process. The power consumption of the circuit was 1.5 mW.

The shear force sensor is one of the key elements in future robotic industries; it is of great importance in applications where robotic arms are required to delicately interact with objects to be handled. This paper presents the development of a capacitive shear force capable of sensing shear forces in two degrees of freedom. The fabrication of the sensor is based on the PCB fabrication process, a well-known and mature technology. We adopt the capacitance sensing scheme for its high sensitivity and easy implementation. For sensor characterization, we used a force gauge and an optical interferometer to measure sensor's parameters including its sensitivity and resolution. The dimension of our prototype shear force sensor including the metal housing is 26 mm × 13 mm × 58 mm suitable for the integration with commercial robotic grippers. For sensor performance, we achieved a shear force sensitivity of 126 fF/N and a resolution of smaller than 6 mN.

Microprobing systems based on silicon force sensors allow accurate force and displacement measurements in the range of several μN or μm. Due to the high sensitive diffused piezoresistors and an appropriate electrical circuitry, these probing systems enable tactile measurement without leaving scratches on the probed surfaces. To probe microstructures on workpieces, probes with probe balls as small as possible are sought. Mostly, commercial microprobes have probe balls with diameters of 120 μm or larger. In this work, microprobes with probe ball diameters down to 50 μm are presented and characterized in detail. In order to verify the performance of these new microprobes, measurements have been carried out to characterize both their mechanical behavior and their sensitivity. These properties have been extensively analyzed for different sensor designs and probe ball diameters. For instance, microprobes with probe ball diameters of 50 μm have a stiffness of about 0.637 mN/μm in X-Y and about 20.023 mN/μm in Z directions of the probe. The sensitivity amounts to 1.174 mV/V/μm and 20.478 mV/V/μm in X-Y and Z directions, respectively. The results presented encourage a new generation of microprobes to be used in dimensional metrology.

We propose an add-drop ring resonator interferometer with high sensitivity. We theoretically demonstrate this add-drop ring resonator configuration with a compact size enables the simultaneously producing fast light and slow light. We also theoretically calculate the sensitivity of the add-drop ring resonator interferometer as a sensing system. The sensitivity of our configuration can achieve 13.48/rad, which is enhanced by 6.46/rad compared to that of the traditional single-bus ring resonator which is 7.02/rad. This proposed structure enables highly sensitive, compact and stable sensors.
