The paper depicts some advanced technologies in order to install a low power consumption and reconfigurable sensor networks, which presents optimal operation and excellent reliability. The results of this paper are prepared during a research project that implements a low power microsystem in package so that the antenna and the radio interface are co-integrated. Consequently, the used instrumentation is designed for small distances, in order to be able to work in restricted areas as space and non-planar zones. A key requirement for the communicating node, which are acted by the sensors network, is to propose a flexible technology able to integrate the CMOS transceiver by Flip Chip onto an organic substrate. For this purpose, the antenna was directly implemented onto a flexible polymer material. The organic substrate selection must be performed in agreement to the radiation diagram of the antenna. As a second aim of this paper, an Organic Thin Film Transistor with pentacene film is simulated to capture the static characteristics and to find the matching parameters for other organic materials. In this scope, an alternative polymer grafted on nano-core material synthesis, is depicted.

Lipase is an enzyme that catalyzes the hydrolysis of fats (lipids) which was synthesized by bacteria in the lab and characterizes using electrochemical analysis by cyclic voltammetry method to find the effect of synthesis lipase in blood medium. It was found oxidation current peak of commercial lipase in blood medium at 0.5 V on glassy carbon electrode versus Ag/AgCl as reference electrodes and scan rate 0.1 Vsec-1, while the oxidation peak of synthesis lipase by bacteria was disappeared in blood medium. So, the synthetic lipase is advisable to be used as a safety enzyme to hydrolyze the lipids in human body avoiding precipitate of cholesterol molecules in blood vessels without any side effect.

In this work, Polycaprolactone (PCL), silver nitrate (AgNO3) and zinc oxide (ZnO) were used for fabrication of a multilayered antibacterial nanocomposite material using co-axial electrospinning (CAE). 5, 10, and 15 wt. % concentrations of PCL were utilized, and varying amounts of AgNO3/ZnO were used in all samples to increase antibacterial activity. Products were analysed using Scanning Electron Microscopy (SEM) to obtain the morphological characterization, and Fourier Transform Infrared Spectroscopy (FTIR) was used to determine the functional groups of the PCL, AgNO3, and ZnO materials in the electrospun nanocomposites. Tensile strength was also determined for each sample. Additionally, viscosity, density, and electrical conductivity were measured for each prepared solution before the CAE process. The antibacterial activity of the fabricated electrospun nanocomposite materials was tested against Staphylococcus aureus and Eschericha coli strains. A simple nanoscale assembly approach was provided using CAE processing to incorporate a variety of AgNO3 and ZnO functionalities into the nanofibers to fabricate biohybrid materials for antibacterial surface applications.
