Electrical capacitance tomography (ECT) is an advanced non‐invasive imaging modality used to visualise the internal distribution of materials by measuring variations in capacitance. The technique has ...

First came electronics, the processing of information in terms of the charge of electrons flowing through circuits. Later a new form of tronics, spintronics, was invented to exploit the magnetic ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Dielectrics are of two types: (i) Non-Polar Dielectrics: When the centre of positive charge coincides with the centre of negative charge in a molecule, e.g., Nitrogen, Oxygen, CO 2 etc. (ii) Polar ...

Capacitive touch sensors are based on the electrical capacitance of the human body. When, for example, a finger comes close to the sensor, it creates a capacitance to Earth with a value of 30 to 100 ...

When not touched, a parasitic capacitance exists in touch electrode between the GND pattern and metallic frame of the PCB around the electrode. The electric capacitance is generated between the touch ...

One day, Dr. Stephen Gass, an avid recreational woodworker and cabinet maker, was using his table saw when his training as a physicist and years of patent-law practice kicked in. He started to think ...

Imec has developed a new failure analysis method to localize interconnection failures in 2.5D/3D stack die with through-silicon vias (TSVs). This technique is called LICA, which stands for ...
