  - Rok 2013

  W celu pomiaru wilgotności szeroko stosowane są czujniki elektryczne. Warstwą czynną, zmieniającą swoje właściwości pod wpływem pary wodnej, stanowią najczęściej materiały ceramiczne lub polimerowe. Tlenek cynku jest jednym z materiałów ceramicznych będących dobrym kandydatem do zastosowania go jako warstwy czynną w czujnikach wilgotności. W tej pracy przedstawiono wyniki badań właściwości struktur czujnikowych z warstwą tlenku...
