Nettetelectroadhesive effect, as it was a highly intensified version of the AC effect. When the term Johnsen-Rahbek effect is used in literature, it solely refers to intensified electroadhesion with DC excitation. An in-depth explanation of the Johnsen-Rahbek effect is beyond the scope of this paper, but a basic explanation is as follows. NettetThis effect, which came to be known as the Johnsen-Rahbek effect, showed considerable promise for application to practical devices such as relays and clutches since large …

NettetH02N13/00 — Clutches or holding devices using electrostatic attraction, e.g. using Johnson-Rahbek effect Abstract An electrostatic chuck includes dielectric layer … NettetGenerally, a Johnsen-Rahbek (J-R) type electrostatic chuck (ESC) generates higher attractive force than a Coulomb type ESC. Attractive force in a J-R type ESC is caused by the high electrical resistance that occurs in the contact region between an object plate and a dielectric layer. NettetThus, the Johnsen- Rahbek effect promotes charge migration, while the electrostatic force that ultimately retains the wafer atop the chuck is the Coulombic force between the charges on the... duke university hospital apparel
