Researchers have found that a system based on ion-sensitive field effect transistors -- a tiny electrical circuit that is activated by a change in pH -- and enzymatic chemical signal amplification can ...

Atomic-scale imperfections in graphene transistors generate unique wireless fingerprints that cannot be copied or predicted, offering a new approach to hardware security for IoT devices.

In this lesson, students search for transistor-based devices at school. They use the results of their search to explain the significance of the transistor in their lives. A transistor is a tiny device ...
