Electrophysiology is the measurement of the electrical activity, or “excitability”, of biological cells (be they muscle cells, neurons, or stem cells). This can be done at a single-cell level, or it ...

Genetically encoded voltage sensors are coming of age, but their use still poses challenges that must be addressed from multiple angles. Neurons process information with the help of electrical signals ...

Potential difference (or voltage) is a measure of energy, per unit of charge, transferred between two points in a circuit. A potential difference of 1 volt means that 1 joule of work is done per ...

The electric potential difference is the difference in electric potential represented by V which shortens the word volt, the unit of measurement of the difference in electromotive force (EMF) or ...

(Nanowerk News) Photothermoelectric (PTE) effect involves two energy conversion processes: photothermal conversion and thermoelectric effect. When the incident light is locally absorbed, a temperature ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

Editor’s note: This month’s guest author is John P. Griffith, a systems engineer for the Interface group at TI, where he has supported CAN and RS485 transceivers in both applications and systems ...
