The sensors are designed in AMI 1.5 mum 2 metal, 2 poly process. A unique maskless post processing sequence is designed and completed. The three post-processing steps are fully compatible with any CMOS technology. This allows any signal control/processing circuitry to be easily integrated on the same chip. ZnO is used as the piezoelectric material for the SAW generation. A thorough characterization and patterning optimization of the sputtered ZnO was carried out. The major novelties that are introduced in the SAW delay line features are: The embedded heater elements for temperature control, compensation and acoustic absorbers that are designed to eliminate edge reflections and minimize triple transit interference. Both of these attributes are designed by using the CMOS layers without disturbing the SAW performance","PeriodicalId":119985,"journal":{"name":"IEEE Sensors, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130353772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A highly sensitive nickel thin film resistor spanning a reactive ion etched cavity in a polyimide foil is employed. This sensor is the first in literature to feature both a thermally insulating cavity and a flexible base material. The polyimide base material allows adopting of the sensor to aerodynamic surfaces, e.g. airfoils and turbine blades. A mismatch of curvature of aerodynamic surface and silicon sensor surface, as observed with previously presented MEMS hot-wire anemometers, is avoided. The combination of polyimide's low thermal conductivity and a cavity featuring FEM-optimized dimensions accounts for a very low power consumption (<30 mW). Fluctuations in wall shear stress up to 80 kHz can be resolved in constant-temperature mode. An average sensitivity of 0.44 V/(N/m2) is achieved in a wall shear stress range from 0 to 0.25 N/m2","PeriodicalId":119985,"journal":{"name":"IEEE Sensors, 2005.","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132079007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of traveling speeds up to 160km/h, fast and sensitive data acquisition is an important prerequisite. Moreover, fire in closed wagons normally has only small, hardly measurable influence on the outer wagon surface, which requires optimized sensing techniques. One promising approach for reliable fire detection on railroad vehicles is the inspection of their surface temperature. Today's high resolution infrared slit cameras can fulfil all requirements regarding measurement speed, accuracy and temperature range. However, the high camera cost is a major disadvantage in deployment in multiple places along the track. With detailed knowledge of the surface temperature distribution under different fire conditions, cameras may be substituted by temperature sensors, which match the measurement issue better and are cheaper.
