In this paper we discuss the fabrication and characterization of miniaturized triglyceride biosensors on crystalline silicon and porous silicon (PS) substrates. The sensors are miniaturized Electrolyte Insulator Semiconductor Capacitors (mini-EISCAPs), which primarily sense the pH variation of the electrolyte used. The lipase enzyme, which catalyses the hydrolysis of triglycerides, was immobili...

Moving to smaller libraries can be considered as a relevant task when porting software systems to limited-resource devices (e.g., hand-helds). Library miniaturization will be particularly effective if based on both dynamic (keeping into account dependencies exploited during application execution in a given user profile) and static (keeping into account all possible dependencies) information. Th...

In a previous study, we concluded that a conductivity based PCO2 sensor is an attractive solution for early detection of ischemia and presented two design geometries. For organ surface measurements, the planar design was suitable but it was difficult to insert the sensor into the tissue. A cylindrical design solution was favored for insertion due to the large membrane contact area and easy plac...

A novel Defected Ground Structure (DGS) is proposed to miniaturize a 2×2 Modified Corporate Feed Planar Antenna Array (M-CFPA) with modified corporate feeding network. The DGS altered the surface current distribution and shifted resonance frequency lower side. After running parametric sweep of length width patch antenna element, achieved miniaturized array resonating at 2.4 GHz frequency. desig...

Since Ion Sensitive Field Effect Transistors (ISFETs) were introduced by Bergveld in 1970, much effort is put into new and improved materials for device optimization and sensitivity enhancement [1]. ISFET based biosensors have a fast response, are suitable for miniaturization and arrays can be made for simultaneous measurement of various parameters. Actually, ISFET device production relies on s...

Miniaturized species have evolved in many animal lineages, including insects and vertebrates. Consequently, their nervous systems are constrained to fit within tiny volumes. These miniaturized nervous systems face two major challenges for information processing: noise and energy consumption. Fewer or smaller neurons with fewer molecular components will increase noise, affecting information proc...

The paper presents research results in the field of small antennas obtained at the Department of Wireless Communications, Faculty of Electrical Engineering and Computing, University of Zagreb. A study comparing the application of several miniaturization techniques on a shorted patch antenna is presented. Single and dual band shorted patch antennas with notches and/or slot are introduced. A PIFA...

This paper puts forward a new design idea of single lens according to the principle of optical triangulation. The minitype laser triangle probe is designed on the basis of the common direct laser triangulation whose light path is improved. A beam splitter lens is introduced to the path,and the focusing lens and imaging lens are into one. The beam splitter lens, detector and focusing lens are co...

The scaling laws associated with the miniaturization of planar inductively coupled plasmas (ICPs) are investigated. The applications for miniature ICPs include microelectromechanical systems (MEMS) for chemical analysis. Langmuir probe and microwave interferometry measurements of three ICPs with coil diameters of 5, 10, and 15 mm show that electron density typically falls in the range of 10 10 ...
