This paper reports a CMOS MEMS (complementary metal oxide semiconductor micro electromechanical system) piezoresistive humidity sensor fabricated by a surface micromachining process. Both pre-CMOS and post-CMOS technologies were used to fabricate the piezoresistive humidity sensor. Compared with a bulk micromachined humidity sensor, the machining precision and the sizes of the surface micromach...

Recent advances in heat flux measurement have resulted in the development of a robust thermopile heat flux sensor intended for use in extreme thermal environments. The High Temperature Heat Flux Sensor (HTHFS) is capable of simultaneously measuring thermopile surface temperature and heat flux at sensor temperatures up to 1000 ◦C. The need for high temperature heat flux calibration of the HTHFS ...

A fiber Bragg grating (FBG) sensor with heat resistance was produced via a point microfabrication technique using a femtosecond pulse laser. The FBG sensor was reinforced by weaving with a carbon fiber tape. As a result, both high strength and a structure for mounting the sensor were readily incorporated. In a high-temperature tolerance evaluation of the FBG sensor, the temperature and strain w...

An energy efficient temperature sensor for constant temperature monitoring has been introduced in this paper. The proposed sensor doesn’t use BJT for sensing; instead it utilizes the temperature dependency of threshold voltage of MOSFETs for designing of this sensor. The sensor circuit is designed with separate biasing circuit for limiting the power dissipation of the circuit. Both PTAT and CTA...

A translucent polyurethane (PU) welding tape used as an e...

This paper puts forward the passive and wireless SiCN temperature sensor in the applicability and necessity of the turbine engine internal environment temperature measurement. Using the principle of resonance frequency scanning tracking method based on perturbation to be the system test method, while the sensor feedback signal and the input signal ratio (S11) parameter as data analysis, and est...

Visit analog.com There are several types of temperature sensors that can be used in a temperature system. The temperature sensor to use depends on the temperature range being measured and the accuracy required. Along with the sensor, the accuracy of the temperature system depends on the performance of the analog-to-digital converter (ADC) to which the sensor is interfaced. A high resolution ADC...

Objective(s): Today, there is an urgent need for improved sensor materials for drug sensing and effective monitoring and interventions in this area are highly required to struggle drug abuse. The present study aimed to synthesize a thioguanine-responsive sensor based on a nanocomposite consisting of AuNP-grafted light- and temperature-responsive poly butylmethacrylate-co-acrylamide-co-methacryl...
