electronics The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification ...

, an Electrolyte–insulator–semiconductor (EIS) sensor is a sensor that is made of these three components: * an electrolyte with the chemical that should be measured * an insulator that allows field-effect interaction, without leak currents between the two other components * a

semiconductor A semiconductor is a material which has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way. ...

to register the chemical changes The EIS sensor can be used in combination with other structures, for example to construct a light-addressable potentiometric sensor (LAPS).
