We have developed ozone (O3) generation system suitable to soil sterilization. Wide range concentration control of O3 is required for the sterilization treatment depending on the soil property and plant growth. The dielectric barrier discharges using electrode such as Pyramid type is studied. Surface discharges are also applied to generate high concentration for quick sterilization of the agricultural soil. The treated soil properties under ozone sterilization were evaluated using pH and electrical conductivity. It is shown that ozone distribution in the soil is controlled mostly by the conditions such as concentration and flow rate as well as soil conditions of moisture and compositions.

In this study, we use the strip-bending test to measure the residual stress of a thin film structure. The principle of the strip bending test and the test procedures are described and the analysis of the strip deformation is presented. The explicit formula for estimating the residual stress is given, which requires the initial stress as an input. As an example, the E-beam evaporated Au thin film is chosen, and the residual stress is measured by the present method. The Au thin film structure has a tensile or compressive residual stress depending on the film thickness. The tensile and the compressive residual stresses of Au thin film are successfully measured by the present method.

Design, simulation, and optimization of a novel (extremely) broad-band coplanar waveguide (CPW)-fed on-chip antenna using genetic algorithm (GA) is presented. The antenna is of slot type and has the shape of a bow-tie with rounded truncation. It is designed on quartz coated silicon substrate and fed with 50 ohms CPW transmission line. Return loss of the antenna is less than -10 dB for most of the frequency range of 5-60 GHz

Recently, a capsule endoscope has been developed to observe images from the inside of intestine. Such a capsule endoscope does not have locomotion or hold method. To get proper diagnosis and medication, it is necessary to control the capsule from outside to guide locomotion. The designed and implemented capsule has feasibility to contract the small intestine by electrical stimuli through the electrodes. When the small intestine is contracted by electrical stimuli, the capsule can move to opposite direction, which means the capsule can go up and down in the small intestine. The implemented stimuli capsule always monitors excessive energy transmission and automatically shuts down the electrical stimuli to make it more secure. Additionally, the stimuli capsule goes on standby mode to save the battery, and it can be reset by comparator circuit which is connected to stimulus electrodes. To verify the design and implement the stimuli capsule, in-vitro experiments were performed with pig's small intestine.

Electrogastrography (EGG) is a significant reference of the myoelectric activity of the gastrointestinal tract and indicates whether it has a disease or not. There have been numerous studies of the myoelectric activity in a stomach, but only a few studies of the intestines because of the difficulty of measurement in the intestines. Recently, the technology of the biotelemetry capsule for measurement of internal information in the human digestive tract has been developed. In the current study, an EGG telemetry system using the developed biotelemetry technology was designed and implemented for measuring EGG in intestines. The EGG capsule converts the acquired EGG value to digital data, which is transmitted from the capsule to the external receiver. The performance of the telemetry capsule for the EGG monitoring in the gastrointestinal tract was verified by in-vitro animal experiments. From the experiment, it was verified that the EGG telemetry capsule can measures a slow wave in intestines.
