Light Dependent Resistance as a Sensor in Spectroscopy Setups Using Pulsed Light and Compared with Electret Microphones
Light-dependent resistances (LDR) are cheap light sensors. A less known light detector is the electret microphone, whose electret membrane functions as a perfect absorber, but only detects pulsed light. The aim of this study was to analyze the use of a LDR and an electret microphone as a light sensor in an optical spectroscopy system using pulsed light. A photoacoustic spectroscopy setup was us...
متن کاملMicromachining of Electret Materials , Advantages and Possibilities
In this pa er we describe a process for the micromachining of materials like Teflon-FEP. We have used photolithography and plasma etching, by which electrets can be etched selemvely. The advantages of, in such a way micromachined electrets are numerous. Miniature sensors like microphones and pressure sensors, containi6 local areas with Teflon, have been realized in our laboratones. The process ...
متن کاملMiniaturized Electrets
This paper describes the realization process of small-size electrets by using techniques generally applied in the fabrication of integrated circuits and microsensors. In the first part of the paper, attention is paid to the different electret decay mechanisms and their relative contribution to the overall stability of miniaturized electrets. Then, a process is described by which polymer electre...
متن کاملMicro Electret Power Generator
We present the first micromachined rotational electret power generator, linearized theoretical model of electret power generation, and novel method to produce uniformly charged electret. We also improved our previously developed [ I , 21 thin film Teflon AF 1601-S electret technology with respect to dielectric thickness, charge uniformity, and processability. In demonstration, our prototype pow...
متن کاملMeasurement of surface alpha contamination using electret ion chambers.
Electret ion chambers are inexpensive, light-weight, commercially available, passive charge-integrating devices for accurate measurement of different radiations. Performance of electret ion chambers for surface alpha contamination measurement was evaluated. Ion chambers of two types and electrets of three thicknesses were used for the study. Calibration of the electret ion chambers was performe...
