Corrosion of carbon steel rebar in concrete structures, such as highways, bridges, and buildings have a direct impact on their structural integrity, since the rebar provides the tensile strength within the structure. Rebar strength depends on the remaining effective cross-section of a given rod. Presence of water and migration of corrosive elements, such as chloride, may result in rebar corrosion with subsequent loss of overall structural strength. In order to adequately quantify the cross-section of the ferromagnetic rod, it is necessary that the transient response is strong enough to be detected. In addition, rebar used in different applications will be placed at different depths from the outermost concrete wall. Examination of long-time decay, on five rebar samples of diameters ranging from 19 mm (0.75 in) to 57 mm (2.25 in), in the transient response of Pulsed Eddy Current (PEC) was examined as a potential method to quantify a maximum liftoff-to-size relationship. The transient response of a coaxial solenoidal drive-receive coil pair, oriented parallel to the rebar axis, was analyzed over a range of liftoffs (distance within the concrete) up to 150 mm. At times greater than ~30 ms, a single exponential decay constant appeared as a constant slope, independent of liftoff in a semi-log plot. The intercept of the linear long-time decay, in semi-log space, decreased exponentially with liftoff, and maintained a viable window for analysis up to 85 mm, 110 mm, 125 mm, 138 mm and 141 mm distances for rebar diameters of 18 mm (0.75 in), 25 mm (1 in), 38 mm (1.5 in), 51 mm (2 in) and 57 mm (2.25 in), respectively. Stated data demonstrate a power law dependence on rebar radius of limits on signal analysis due to liftoff. This report shows the potential for PEC analysis to quantify the cross-sectional area of rebar in concrete structures up to size-dependent threshold depths.

This paper reports a novel approach for assessing the surface profile of roads utilizing the vehicle level sensor. The sensor is already legally binding installed in modern vehicles with headlights including LED and Xenon lighting sources in Europe due to the automatic luminaire width control. The effective application of the presented sensor setup is validated within a laboratory setup displaying and simulating the quarter-vehicle-model for known surface profiles while comparing the simulated results with measured values from the sensor setup. The results show that the measured data are in accordance to the general characteristic of the signals frequency and slope. The amplitudes derivate slightly due to inertia in the laboratory setup. This paper shows that the approach of utilizing the vehicle level sensor for road condition monitoring works in principle. It is the first step towards a real-time modelling of road conditions from common vehicles utilizing given sensors.

Low cost devices such as accelerometers, gyroscopes, or force sensing resistors have been exploited to build wearable systems for gait analysis. These sensors are sometimes mounted on a cane if it is required. This paper proposes the use of a tactile sensor on the cane handle to obtain information about gait phases. Moreover, since the sensor is located at the human-device interface, any shaping of the force at this interface that anticipates the movement can be registered. Experimental results from an instrumented cane are presented to illustrate this behavior that can be exploited in applications that involve closed loop control.

For the first time, we conduct theoretical and experimental analysis on the z-axis (out-of-plane direction) acceleration detection of the micro thermal convective accelerometer (MTCA). Instead of using the complex assembling method to make an out-of-plane detection structure, an indirect way to measure the z-axis acceleration is proposed. The mechanism is proposed with the evidence that the sum of the upstream and downstream detectors’ temperature keeps the same under in-plane acceleration, while their differential output keeps constant with the out-of-plane (z-axis) acceleration. By means of monitoring the variation of temperature of in-plane detectors under out-of-plane acceleration, the z-axis acceleration could be indirectly sensed. Theoretically, the coupling error on z-axis induced by x-axis is quite small (less than 1%). Through this method, it could be easy to convert a single-axis (X) MTCA to a two-axis (X-Z) MTCA, which is also promising to improve the two-axis (X-Y) MTCA to a tri-axis (X-Y-Z) accelerometer. In addition, an MTCA is fabricated based on a CMOS compatible fabrication method and demonstrate the proposed detection mechanism with high sensitivity for both x-axis (1211μV/g) and z-axis (402μV/g).
本文首次对微热对流加速度计(MTCA)的z轴(面外方向)加速度检测进行了理论和实验分析。提出了一种间接测量z轴加速度的方法，取代了用复杂的装配方法制作面外检测结构的方法。在平面内加速度下，上游和下游探测器的温度总和保持不变，而它们的差分输出在平面外(z轴)加速度下保持不变。通过监测面内探测器在面外加速度作用下的温度变化，可以间接感知z轴加速度。理论上，由x轴引起的z轴耦合误差很小(小于1%)。通过这种方法，可以很容易地将单轴(X) MTCA转换为两轴(X- z) MTCA，这也有望将两轴(X- y) MTCA改进为三轴(X- y - z)加速度计。此外，基于CMOS兼容的制造方法制备了MTCA，并验证了所提出的检测机制在x轴(1211μV/g)和z轴(402μV/g)上都具有较高的灵敏度。

We describe ongoing research in developing audio classification systems that use a spiking silicon cochlea as the front end. Event-driven features extracted from the spikes are fed to deep networks for the intended task. We describe a classification task on naturalistic audio sounds using a low-power silicon cochlea that outputs asynchronous events through a send-on-delta encoding of its sharply-tuned cochlea channels. Because of the event-driven nature of the processing, silences in these naturalistic sounds lead to corresponding absence of cochlea spikes and savings in computes. Results show 48% savings in computes with a small loss in accuracy using cochlea events.

This paper presents a portable sensor system to monitor unbalanced head postures of long-distance drivers. The head posture monitoring enables driver fatigue analysis (avoiding potential car accidents) and prevents chronic fatigue and possible neck related diseases. A three-axis MEMS magnetometer and miniature magnet are attached on a user’s neck. The user conducts driving scenarios consisting of five common driving actives and one inconvenient posture. Collected magnetometer data are proceeded by neural network algorithms. Part of the data are used to develop a learned model and rest of them are used to calibrate the model. Experiment results are very promising and exhibit superior model accuracy as high as 93.0%.

This paper shows the development and characterization of a 3D-printed flexible finger tip sensor that measures both shear and normal forces. The sensor is fabricated using three material fused deposition modelling (FDM) 3D-printing. The sensing principle is based on the mechanical deformation of the finger tips caused by normal and shear-forces. Therefore, the sensor is flexible and can measure the interaction forces between the environment and the finger tips, while keeping the loss of touch sensation low. Characterization shows the sensor is capable of distinguishing between normal and a shear-force components.

The paper-based sensor provides the functions of reagent storage, sample transportation, and DNA amplification. The compact and low-cost fluorescence detector can quantify the amplicons in real time. The results show that the paper-based sensor can detect genomic DNA extracted from Escherichia coli with the concentration as low as 2 × 104 copies/ µL. As a diagnosis tool, the sensor has the potential to measure multiple target genes simultaneously.

In this work, we proposed a liquid operating TPoS MEMS resonators with on-chip dummy resonator patterns. The fabricated plate type resonators achieve high Q factors in length extensional mode under vacuum, air and liquid environment. With the proposed on-chip dummy resonator patterns, the anti-resonance peak near the resonant frequency was effectively cancelled and Q factors were improved. A resonator with 400 μm and 600 μm plate length shows a Q factor of 10,072 and 14,435, respectively, under 1.0 mTorr. Q factors in liquid phase were measured 71 and 98 in Ethanol, respectively. It was also confirmed that the Q factors in liquid phase varied with the types of liquids (according to their viscosity and density).

A novel Doppler based speed measurement technique for free-ranging acoustically tagged fish was developed and validated through a field experiment in a marine aquaculture farm. For emulated swimming speeds in the range 25cms−160cms−1, an rms error of 5cms−1 with a standard deviation of 4.7cms−1 was achieved, and with a relative error typically less than 10% of measured speed. The technique is designed to integrate easily with existing acoustic fish telemetry systems and requires only three hydrophones to determine swimming speeds. Measurement of fish swimming speed has a wide range of applications within fisheries sciences and may become a valuable tool for assessing fish behavior and performance in marine farms.
