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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

Sodium is used as a coolant in Fast Breeder Reactors. Eddy Current Flowmeter (ECFM) is used for measurement of sodium flow in the primary pump and at the outlet of the subassemblies. Eddy Current Flowmeter (ECFM) works on the principle of change in the magnetic field profile due to ... 詳細を見る

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 ... 詳細を見る

Microheaters used for gas sensing applications have been studied analytically and experimentally. Previously reported microheaters at COMSOL® conferences have shed light on microheaters’ thermal properties, optimized geometries and power consumption—all based on steady-state analysis. In ... 詳細を見る

When a dual probe heat pulse (DPHP) sensor is installed near the soil-atmosphere interface, the basic assumptions of the infinite line heat source (ILS) model and its improvement, the infinite line heat source model with an adiabatic boundary condition (ILS-ABC), might not be satisfied ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る
