Abstract Direct attachment of piezoelectric transducers on hot targets raise formidable challenges as piezoelectric materials will lose their piezoelectric characteristic at elevated temperature due to Curie temperature limitation. In this paper, an attempt was made to build an integrated probe for hot target which enables to alleviate innovatively the Curie temperature limitation. In addition,...

A clustering method is an effective way to select the proper temperature sensor location for thermal error modeling of machine tools. In this paper, a new temperature sensor clustering method is proposed. By analyzing the characteristics of the temperature of the sensors in a heavy floor-type milling machine tool, an indicator involving both the Euclidean distance and the correlation coefficien...

In this study, a system for monitoring the structural health of bridge deck and predicting various possible damages to this section was designed based on measuring the temperature and humidity with the use of wireless sensor networks, and then it was implemented and investigated. A scaled model of a conventional medium sized bridge (length of 50 meters, height of 10 meters, and with 2 piers) wa...

While the satellite data and meteorological measurement are more easily available, there is a lack of comprehensive framework that provides an estimated air temperature map with ease of use to the end-users. This study focus on the developing of a comprehensive web based framework for estimating air temperature map from MODIS LST evaluated relationship with in-situ data collected over a distrib...

In this contribution we deal with technology potential of the low temperature co-fired ceramic (LTCC) in association with design, development and production of organometallic thick film gas sensors. Customer demands to the gas sensors array and to the joint construction of the sensing part with evaluating ASIC led to the exploitation of LTCC potential in the production technology. The presented...

BACKGROUND Intracranial pressure (ICP) monitoring is very important for assessing and monitoring hydrocephalus, head trauma and hypertension patients, which could lead to elevated ICP or even devastating neurological damage. The mortality rate due to these diseases could be reduced through ICP monitoring, because precautions can be taken against the brain damage. OBJECTIVE This paper presents...

Time synchronization in embedded sensor networks is an important service for correlating data between nodes and communication scheduling. While many different approaches to the problem are possible, one major effect of clock frequency difference between nodes, environmental temperature changes, has often been left out of the solution. The common assumption that the temperature is static over a ...

In this work, a novel approach is presented for measuring relative temperature variations inside the pixel array of a CMOS image sensor itself. This approach can give important information when compensation for dark (current) fixed pattern noise (FPN) is needed. The test image sensor consists of pixels and temperature sensors pixels (=Tixels). The size of the Tixels is 11 μm × 11 μm. Pixels and...

Making several simultaneous measurements with different kinds of sensors at the same location in a solution is difficult because of crosstalk between the sensors. In addition, because the conditions at different locations in plant beds differ, in situ measurements in agriculture need to be done in small localized areas. We have fabricated a multimodal sensor on a small Si chip in which a pH sen...

In this study, we have measured temperature distribution using infrared optical fibers during radiofrequency ablation (RFA). Infrared radiations generated from the water around inserted electrode are transferred by silver halide optical fibers and are measured by a thermopile sensor. Also, the output voltages of a thermopile sensor are compared with those of the thermocouple recorder. It is exp...
