Micro-Electro-Mechanical system (MEMS) can be understood as miniaturized mechanical and electromechanical elements that include sensors, actuators, and microelectronics. Capacitive accelerometers are the devices which measure the acceleration on a surface using capacitive sensing ... En savoir plus

Designing and constructing a lab-on-a-chip device poses a variety of questions. Transport of all required substances, detection of the analyte and its deposition on a sensor have to be incorporated. Different strategies have been developed to achieve good coverages of the sensor, like ... En savoir plus

The aim of this work is to present a model capable to describe the behaviour of a thermal flow sensor under every physical aspect. A generic thermal flow sensor relates the flow properties with a variation in the temperature profile inside the device itself. Thus, it is locally heated ... En savoir plus

Recent rapid progress in MEMS with wireless communication system has enabled low power micro sensor network for human body, Body Area Sensor Network (BASN). The information gathering from BASNs will provide a significant opportunities for various medical applications. One of the key ... En savoir plus

Micro-machined ultrasound transducers have a wide range of applications. As a sensor or actuator they can be used for measuring fluid speed and direction, to mix and excite particles (sonication), for taking images (ultrasonography), for non-destructive testing and many other purposes in ...

Smart fabrics enable the integration of electronics into fabric. They can serve as a suitable sensor providing around-the-clock assistance for the real-time monitoring of health parameters. Here, we aim to develop a free-standing piezoelectric cantilever sensor integrated into ... En savoir plus

Rebar detectors are used extensively by construction contractors to locate rebars while drilling, coring or cutting in RCC to avoid causing damage to the reinforcement steel. These detectors are also used by inspection engineers for spot checking of civil infrastructure. Most cost ... En savoir plus

Microfabricated planar interdigitated electrodes can detect and analyze cells or particles giving an impedance-based characterization. This method presents several advantages: real-time detection, label-free analysis, non-invasive sensing, easiness of integration and high-throughput ... En savoir plus

This work aims to determine optimized configuration using COMSOL Multiphysics® for a class of transducers. Two types of capacitive sensors needed for monitoring and control in agriculture are investigated: a rain sensor and a soil humidity sensor. COMSOL Multiphysics® is used to test ... En savoir plus

Gas sensor arrays based on metal oxides operating at high temperature are commonly used in many application fields. They can operate on different principles and each sensor may show very different responses to the individual gases in the environment. Data coming from the array can be ... En savoir plus
