    Pneumatic Artificial Muscles (PAMs) have been known for its wide application in various aspects of industrial automation and robotic equipments. Many advantages in terms of high power-to-volume ratio, high power-to-weight ratio, stick-slip-free operation and high degree of safety offer by PAM compare to traditional actuators. However, behind this benefits lie a limitation of significant compatibility of PAM mechanism which have to be considered so as to fully understand how the PAM works during load-lifting. In this study, the mesh suitability experiment and the effect of force load on PAM contraction experiment have been carried out. PAM is constructed and compatibility of bladder and the braided mesh to produce uniform expansion is investigated. Moreover, the first experimental result of finding compatibility is used to verify the contraction value under various loads.

    Atmospheric plasma processing are widely used for improving surfaces properties. Cubic silicon carbide (3C-SiC) is one of the material used as biosensor for their biocompatibility properties. In this work, we present the results of atmospheric plasma processing treatments using gas mixture on 3C-SiC surface. The 3C-SiC samples were treated at different duration and flow rate. Helium/Nitrogen and Argon/Nitrogen gas mixtures were used as plasma treatments and its effect on the surface was investigated. A significant increment of surface wettability were observed after plasma exposition. Investigation by surface morphological measurements was performed by using Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM). Contact angle measurement results showed a decreased in contact angle with increasing of treatment time and flow rate, and Argon/Nitrogen mixture promote more wettability compared to Helium/Nitrogen mixture.

    An atmospheric plasma system using Helium gas was developed. The effect of helium plasma treatment on skin scaffold surface was studied by scanning electron microscopy (SEM). The changes of skin scaffold surfaces before and after helium plasma treatment was recorded. The surface of skin scaffold changed with the prolonged of helium plasma treatment time. The depth of helium plasma penetration was studied using methylene blue dye staining method. The methylene blue will detect the presence or absence of an oxygen that was induced from plasma excitation. The presence of the oxygen indicated on the depth of helium plasma penetration. Results showed plasma are able to penetrate 4mm of skin scaffold after 1200 seconds of exposure.

    Many researches had been conducted to enhance the properties of contact lens. Most of the research conducted discussed on the factors that affect the adhesion process to contact lenses, rate of contact lens contamination, and type of microbe that adhere on the contact lens surface and contact lens casing. Studies on the proposed strategies or technology that can be used to slower down the formation of bacteria on contact lens are being explored. New technologies or strategies to prevent or slow down the adhesion of bacteria on contact lens have become a priority in this area. This review paper covers two main aspects, namely factor that affect the bacteria adhesion on contact lens and also the introduction of plasma treatment as a potential method for contact lens treatment.

    Review papers on the basic principles and applications of plasma discharge in liquid have been reported. However, the development of plasma discharge in liquid is not widely reviewed. The aim of this paper is to review on the elements involved in developing plasma discharge in liquid. An overview will be given of the various types of existing power source, working gas, dielectric barrier, electrode material used to produce plasma, and reactive species production inside plasma discharge.
