Corn moisture content is the main factor of effecting corn safe transportation and storage, and is also an indispensable measurement part when it is used to feed, food and industry. Due to large particle size, corn will produce large gap during measuring moisture content. Because air has much influence on dielectric constant of the device, moisture content is not precision. In all kinds of corn...

A transmitter front-end IC for ultrasound medical imaging applications is implemented using 30-V 0.18-mm Bipolar/CMOS/DMOS process. The proposed ultrasound transmitter front-end, consisting of voltage level-shifters and an output driver, achieves high integration and maintains good reliability while generating a 33 ns output pulse signal in order to drive a large capacitive load, which represen...

Research, design, fabrication and results of various screen printed capacitive humidity sensors is presented in this paper. Two types of capacitive humidity sensors have been designed and fabricated via screen printing on recycled paper and cardboard, obtained from the regional paper and cardboard industry. As printing ink, commercially available silver nanoparticle-based conductive ink was use...

The rapid and efficient exchange of ions between porous electrodes and aqueous solutions is important in many applications, such as electrical energy storage by supercapacitors, water desalination and purification by capacitive deionization, and capacitive extraction of renewable energy from a salinity difference. Here, we present a unified mean-field theory for capacitive charging and desalina...

Since the discovery of Cole and Curtis (1938. Nature (Lond.). 142:209 and 1939. J. Gen. Physiol. 22:649) that the imaginary components, i.e., capacitive and inductive components, of the admittance of squid axon membrane remained unchanged during the action potential, there have been numerous studies on impedance and admittance characteristics of nerves. First of all, it is now known that the di...

The capacitive effects of a ground plane on an aerial bucket truck undergoing periodic testing can have a significant impact on the measured test results. The capacitive coupling of a building can reduce the leakage current through the boom resulting in a lower reading from the return point of the truck. Since the coupling is not as prevalent outdoors, more current flows through the boom result...

This paper proposes a new method for the measurement of spherical coordinates by using capacitive sensors as a non-contact probe solution of measurement of aspheric surfaces. The measurement of the average effect of the capacitive probe and the influence of capacitive probe tilting were studied with respect to an eccentric spherical surface. Based on the tested characteristic curve of the avera...

This paper investigates the use of capacitive proximity sensors as sources of contact-free feedback signal measurement for active vibration attenuation applications. An experimental laboratory device is introduced, which consists of a clamped cantilever beam and actuated by bonded piezoelectric actuators. A measurement model is created and experimentally verified for the assessment of beam tip ...

Several approaches to generate electrical power directly from salinity gradient energy using capacitive electrodes have recently been developed, but power densities have remained low. By immersing the capacitive electrodes in ionic fields generated by exoelectrogenic microorganisms in bioelectrochemical reactors, we found that energy capture using synthetic river and seawater could be increased...
