The duration of moisture retention on mock leaf sensors made from electrical impedance grids was purposely manipulated by changing the color and angle of deployment of these sensors. The duration of moisture retention varied up to 2 h 50 min, depending on the type of moisture deposited (rain or dew) and the conditions during drying. Comparisons were made with onion (Allium cepa L.) foliage where a very light gray mock leaf indicated complete drying of the crop with a maximum error of 27 min while a DeWit Leafwet Recorder had a maximum error of 90 min. A simple AC-powered circuit for recording leaf wetness is described. Also, for use in remote locations, a battery-powered system was constructed that utilized integrated circuits for low power consumption.

The development of microelectromechanical system (MEMS) processes enables the integration of capacitive sensors into silicon integrated circuits. These sensors have been gaining considerable attention as a solution for mobile and internet of things (IoT) devices because of their low power consumption. In this study, we introduce the operating principle of representative capacitive sensors and discuss the major technical challenges, solutions, and future tasks for a capacitive readout system. The signal-to-noise ratio (SNR) is the most important performance parameter for a sensor system that measures changes in physical quantities; in addition, power consumption is another important factor because of the characteristics of mobile and IoT devices. Signal power degradation and noise, which degrade the SNR in the sensor readout system, are analyzed; circuit design approaches for degradation prevention are discussed. Further, we discuss the previous efforts and existing studies that focus on low power consumption. We present detailed circuit techniques and illustrate their effectiveness in suppressing signal power degradation and achieving lower noise levels via application to a design example of an actual MEMS microphone readout system.

Circuit Resistance

<p>As CMOS technology is continuously becoming smaller and smaller in nanoscale regimes, and circuit resistance to changes in the process for the design of the circuit is a major obstacle. Storage elements such as memory and flip-flops are particularly vulnerable to the change process. Power consumption is also another challenge in today's Digital IC Design. In modern processors, there are a large number of transistors, more than a billion transistors, which increases the temperature and the breakdown of its performance. Therefore, circuit design with low power consumption is a critical need for integrated circuits today. In this study, we deal with GDI techniques for designing logic and arithmetic circuits. We show that this logic in addition to low power consumption has little complexity so that arithmetic and logic circuits can be implemented with fewer transistors. Various circuits such as adders, differentiation and multiplexers, etc. have been designed and implemented using these techniques, and published in various articles. In this study, we review and evaluate the advantages and disadvantages of these circuits.</p>

Shim Coil

It is necessary to develop a high homogeneous, low power consumption, high frequency and small-size shim coil for high precision and low-cost atomic spin gyroscope (ASG). To provide the shim coil, a multi-objective optimization design method is proposed. All structural parameters including the wire diameter are optimized. In addition to the homogeneity, the size of optimized coil, especially the axial position and winding number, is restricted to develop the small-size shim coil with low power consumption. The 0-1 linear programming is adopted in the optimal model to conveniently describe winding distributions. The branch and bound algorithm is used to solve this model. Theoretical optimization results show that the homogeneity of the optimized shim coil is several orders of magnitudes better than the same-size solenoid. A simulation experiment is also conducted. Experimental results show that optimization results are verified, and power consumption of the optimized coil is about half of the solenoid when providing the same uniform magnetic field. This indicates that the proposed optimal method is feasible to develop shim coil for ASG.
