The aim of this paper is to understand how lower limb proprioception effects a dual task paradigm, while maintaining postural stability. A dual task paradigm involving collision avoidance and maintaining stability in single limb stance have been designed as a Virtual Reality game, using Kinect and played with ‘Google Virtual Reality’ device. Five healthy subjects played the game for four consecutive days. Neural interplay and effect of proprioceptive adaptation were modeled in terms of muscle co-activation, sway of Centre of Mass, collision rate and a smoothness function of knee joint trajectory. Findings from this study would help to better understand the dual task paradigm for lower limb, task prioritization and effect of proprioceptive adaptation on motor task.

This study presents the approach to implement an electromagnetic type active wireless CMOS-MEMS tactile sensor. The tactile force applied on sensor will deform the flexible polymer and further cause the displacement of rigid chrome-steel ball. Thus, the magnetic flux and the voltage of sensing coil induced by the driving coil are changed, which are employed to measure the tactile load. The proposed tactile sensor has four merits: (1) flexible polymer filler as spring, (2) rigid chrome-steel ball as movable sensing interface (for loading and introducing magnetic flux change), (3) CMOS chip as sensing unit, and (4) sensitivity is enhanced by increasing the driving voltage. Note: no suspended thin film structures are required. The presented design is implemented by the standard TSM C O.18μm CMOS process. Measurements indicate the sensitivity of tactile sensor (with 5Vpp driving voltage) is O.53mV/N with loading range of 0-2.4N.

The field of environmental perception is an important task to allow autonomous vehicle to navigate safely in crowded urban environments. Since the sensory technology is established for several years the main task lies in the data analysis. Especially imaging sensors collect a huge amount of data that contains a high redundancy. Due to this, the generation of an of a environmental picture with imagine sensors is challenging an requires sufficient computational Power. A possible solution is to distribute the necessary calculation on several smaller computational units, where each of them analyses only a part of the data. From this follows a higher bandwidth demand to the communication system since the data must be transmitted between the computational units. In this work a Region Growing Algorithm is combines with a Randomized Hough transformation to extract planes from a 3D-point cloud. Additionally the software can reduce the amount of data that must be transmitted in distributed computing environments since redundancy is removed. This reduction is done with Grahams scan algorithm that generates a Polygon describing the extracted Plane.

In this paper, we show the feasibility of using an off the shelf short range automotive radar working at 24GHz frequency for through-wall mapping. For this purpose, an enclosed arena made of portable wall segments was constructed, creating various indoor wall configurations, and these were probed from the outside using the radar mounted on the top of a differential drive robot. It was shown that the radar can detect most wall segments hidden behind the outer walls, and the robot can construct a 2D map of the environment in sufficient detail probing the environment with a short range radar from multiple known positions.

Real-time monitoring of environmental exposure causing chronic diseases including asthma and COPD has assumed enormous significance due to prolific advances in materials science and electronics. Such monitoring demands low-power electronic devices for signal conditioning and measurement to be integrated with state-of-the-art environmental sensors. Ozone is a known trigger of asthma causing significant health burden worldwide. In this paper, sensitive detectors based on functionalized (i.e. high specificity) single-walled carbon nanotubes are designed to measure ambient ozone exposure. The electronic interface comprises low-power integration of the chemical sensor with a commercial device to measure the complex (sensor) impedance at a frequency between 40 kHz and 1 MHz. Simultaneous measurement of magnitude and phase on several ozone sensors reveal response change of 35% in the former and 80% in the latter, and a detection limit of only 10 ppb. This innovative chip-based impedance measurement technique has the potential for characterizing the personal exposure to ambient air pollution triggers of respiratory diseases.

A flexible, lightweight and minimally intrusive monitoring system has been developed to assess animals' behavioral responses. The system consists of wearable composite magnets and magnetic sensors integrated into a miniaturized wireless communication module with a flexible battery. The shape and size of the NdFeB-PDMS composite magnets are highly versatile, while the magnetic and mechanical properties can be tailored within a wide range by the powder concentration. The magnetic field of the composite magnet is sensed by a 3-axial magnetic sensor, and the measured data is wirelessly transmitted using Bluetooth low energy communication standard to a smartphone and dashboard. To withstand corrosive environments and enhance the durability the composite magnets are coated with 2 µm of Parylene C, while surface passivation of the wireless module is achieved with 5 µm of Parylene C. The system has been implemented for real-time monitoring of crabs, giant turtles, and giant clams, indicating its potential for novel and affordable animal monitoring applications.

In this paper, we will be focusing on the application of sensor communication by implementing Bug algorithms into motion planning and search-based planning. We have learned and researched about the bug algorithm family and then applied the algorithm into programming a robot. For this project, we will be programming a RP6 Robot kit with one of the three bug variation: bug 1, bug 2 and tangent bug so that it can move from a known starting point to a known end point while navigating an unknown obstacle course between the two points. This project is an introduction to the field of motion planning in robotics, which provides the basics for building a fully-automated robot with environmental awareness. Not included in this project is discussion of other motion planning algorithm family, this paper focuses solely on the bug algorithm and its programming application.

Zero-power infrared (IR) sensors based on Plasmonically-enhanced Micromechanical Photoswitches (PMPs) have recently been demonstrated, showing the capability to detect IR signatures with near-zero standby power consumption. However, current prototypes fail to discriminate between a targeted IR source (e.g. a flame) and a spurious one (e.g. an exhaust plume) having overlapping IR emission wavelengths, potentially getting triggered ON in the presence of strong interference and creating false alarms. This paper reports on the first experimental demonstration of a PMP augmented with an integrated passive false-alarm prevention mechanism to effectively desensitize it to spurious IR sources while maintaining a small footprint and near-zero standby power consumption. By incorporating two different narrowband plasmonic absorbers on a PMP - one tuned to the targeted IR wavelength and the other to a spurious wavelength - we show that the electrical contacts close in response to IR radiation at the targeted wavelength and remain open in the presence of spurious wavelengths, thereby preventing false alarms. Such an enhanced PMP prototype targeting flame detection with a threshold ~600 nW (minimum detectable IR power) is demonstrated showing zero false alarm to interfering IR sources. The increased reliability enabled by this technique makes PMP technology an ideal candidate for the implementation of large-scale maintenance-free wireless sensor networks with unlimited battery lifetimes.

This work demonstrates a new architecture adopting a modified double side-band (MDSB) demodulation configuration to gain drive mode amplitude and phase information. Compared to conventional double side-band (DSB) demodulation configuration, it is robust against phase variation of capacitance-to-voltage (CV) interface circuit caused by environmental parameter changes. Theoretical analysis for gyroscopes using MDSB reveals that the amplitude information for AGC loop and phase information for PLL are both independent of the phase delay of CV circuit. Further, the exact phase delay information of CV circuit using MDSB is also extracted which serves as temperature information of the circuit self-heating process. Comparative experiments of the same gyroscope based on MDSB and DSB configurations in drive mode are conducted using a fully decoupled MEMS tuning fork gyroscope. Experimental results indicate that bias drift including the power-on process using MDSB is improved by about 3 times.

In this paper, a self-test method is proposed for the thermopile infrared (IR) detector. To verify the validity of the self-test method, a high-performance thermopile infrared detector based on XeF2 front-side dry etching is designed, fabricated and characterized. And a platinum heater is fabricated in the absorption area of the thermopiles to replace the traditional IR radiation to monitor the IR performance of the detector. IR radiation sensing is carried out to characterize the $mathbf{IR}$ performance of the thermopile IR detector. The testing results show that the detector achieves a relatively high responsivity of 160.03 V/W and detectivity of $pmb{9.75times 10^{7}}$ cm $mathbf{Hz}^{pmb{1/2}}pmb{cdot mathrm{W}^{-1}}$ and an extremely short response time of 2.5 ms in the air at room temperature. Moreover, the self-test measurement is conducted by applying a voltage to the heater. Compared with the use of complex equipment such as blackbody and chopper to detect the performance of thermopile infrared detectors, this method has obvious convenience and simplicity, which provides an effective way for performance monitoring of thermal-based devices.
