Environment friendly thick film NTC thermistors based on spinel-type Semiconducting electroceramics compositions based on oxides of (Mn, Co, Ni) were fabricated on cyclindrical/rod type alumina substrate. Prepared rod type NTC thermistors were characterized by X-ray diffraction, and Scanning electron microscopy with energy depressive Xray analysis. Rod thermistor samples showed compact and homogeneous microstructure. The electrical parameters such as device resistance, thermistor constant, ageing, thermal cycling, and humidity testing of the thermistors were determined.

Integrated SnO2: CuO thin-film based H2S gas sensor has been realized using low temperature co-fired ceramics (LTCC) tapes with heater and thermister buried inside the LTCC multilayer structure. The SnO2: CuO thin films are deposited on top of the structure. At operating temperature of 180°C, these films revealed sensing properties very similar to the reference films deposited on Alumina substrates. Further, effect of operating temperature on sensitivity was studied and sensor films on LTCC substrate were found to detect H2S with maximum sensitivity at a lower operating temperature of 100°C. The developed sensors have been tested for a period of more than one year and found to show a stable response.

Among the alternative fuels, biodiesel and its blends are considered suitable and the most promising fuel for diesel engine. The properties of biodiesel are found similar to that of diesel. Many researchers have experimentally evaluated the performance characteristics of conventional diesel engines fuelled by biodiesel and its blends. The biodiesel production process requires simultaneous real time monitoring of certain properties like viscosity, acid number, iodine value, moisture content etc, such that the values are within ASTM standards. Therefore, an automated Biodiesel plant fitted with new innovative biosensors have been proposed which could make real time decision taking ability and monitor the overall production mechanism. The control system of the biosensor and production process was coupled with ARTIFICIAL NEURAL NETWORK (ANN). The proposed system have capability to detect 8 different starting oil samples and optimizes itself the best production yield of biodiesel. Therefore, the optimizing problems of the quality of initial feed of vegetable oil used for production of biodiesel are overcome. This paper provides experimental knowledge on the enormous studies for the development of advanced reactor system engineering for large scale production of biodiesel for commercial purpose.

Densification process of Mn-Cr-O negative temperature coefficient (NTC) ceramic compositions in presence of Bi2O3 as a sintering aid and also as a dopant was studied. Bi2O3 (3.8mole %) decreased the sintering temperature of the phase pure MnxCr3−xO4 compositions and obtained more than 95% of theoretical density. Electrical characteristics of the compositions were evaluated and it is found that Bi2O3 addition improved NTC properties, thus making these more suitable as temperature sensor.

Micro-cantilevers are one of the most fundamental building blocks of many applications in the field of MEMS sensors and actuators. They are extensively explored micro-structures and yet, the most interesting ones in terms of their analytical elegance and probable applications in various domains. In this work, a detailed account, starting from the theory of micro-cantilever beams to their applications, has been investigated. The dynamic/modal response of the cantilevers under different damping mechanisms and the effects of their dimensions and the surrounding atmosphere have been analytically and experimentally investigated for arrays of cantilevers of wide range of dimensions [1]. Static response of the cantilevers under electrostatic actuation mechanism has been analyzed based on the Euler- Bernoulli beam theory. An integro-differential semi-numerical technique to solve the Euler-Bernoulli equation to find the static deflection of micro-cantilevers under electrostatic actuation has been presented [2]. An analytical technique to account for the effects of stiction forces on the static response of the beams has also been developed based on the above formulation [3]. For transient response analysis of the cantilevers, a distributed R-C ladder network model of the cantilever has been developed in which, by numerically co-solving Kirchhoff's current and voltage laws and the Euler-Bernoulli equation, the switching response of the cantilever has been thoroughly analyzed [4].

Prognostics is the process of predicting the future reliability of a product by assessing the extent of deviation or degradation of a product from its expected normal operating conditions. Health monitoring is a process of measuring and recording the extent of deviation and degradation from a normal operating condition. Traditional reliability engineering has attempted to quantify reliability as a failure probability and physics of failure based reliability assessment determines a range of possible times to failure. However, each product experiences its own unique life cycle that impacts its rate of degradation. With sensors as the eyes and ears to determine the actual environment, on board or off site computational platforms, and algorithms to process the information give us the ability to assess the reliability of each product and make operations, maintenance, and support decisions in an individualized manner. This talk with introduce the science and mathematics of prognostics and provide examples of use of the tools and techniques as applied in various applications such as batteries, fans, power electronics, and computers. It will also provide information on the development process of the IEEE standard on prognostics for electronics.

Thin film of cobalt phthalocyanine (CoPc), iron phthalocyanine (FePc) and CoPc-FePc composite were grown on sapphire substrate by molecular beam epitaxy under identical experimental conditions. Composite films showed very high mobility ∼ 110 cm2V−1s−1 at room temperature, which is nearly two orders of magnitude higher as compared to the pure CoPc and FePc films. We demonstrate that due to high mobility of composite phthalocyanine films, it showed enhanced sensitivity for chlorine (Cl2) gas as compared to pure CoPc and FePc films

A direct covalent immobilization of glucose oxidase was performed on carboxylated boron doped diamond (BDD) film using 1-Ethyl-3-(dimethylaminopropyl)-carbodiimide (EDC). The carboxylated BDD film deposited using the microwave plasma CVD was obtained by the chemical treatments of oxidization and hydrolysis. The immobilized glucose oxidase was confirmed by a spectrophotometric assay to have the enzyme activity on the BDD film. The activity of the immobilized glucose oxidase indicated long term stability. In addition, the glucose concentration was electrically detected using a redox reaction to the activity of the immobilized glucose oxidase during electrochemical measurements. Carboxylated BDD film allows a short and simple attachment of biomolecules, and leads to development of biomolecules-based biosensors or bio-chips.

Nickel manganite based negative temperature coefficient (NTC) thermistor compositions are extensively used as thermal sensors in a wide range of products and devices. Ni0.701Mn1.823Cr0.35Fe0.07Si0.056O4 NTC thermistor composition was prepared through solid state route. The tape casting slurry composition was optimized to get defect free ceramic tapes. Chip thermistors were prepared from these NTC tapes by optimizing the process parameters. The prepared chip thermistors were encapsulated in borosilicate glass to form Chip-in-Glass thermal sensors with high material constant and excellent reliability.
