Plessey launches range of unique electric field sensors

Purpose The purpose of this paper is to provide details of a high sensitivity electric field sensor developed by Plessey Semiconductors. Design/methodology/approach Following a background to the sensor's origins, this paper describes the principle of operation and then discusses three recently launched products and their applications. Finally, a range of other potential uses are considered. Findings This shows that the sensors offer the unique ability to detect very low electric fields, with or without physical contact. Products have been launched which are finding applications in healthcare and motion detection but many other uses are anticipated in such diverse areas as material testing, forensics, automotive safety, analytical technology and even earthquake prediction. Originality/value The paper describes a new type of electric field sensor which has the potential to satisfy a diversity of medical and industrial applications.
