5. Flexible electronic componentsFlexible electronic components
Electronic components such as transistors are being made from silicon
nanomembrane usually called TFTâs(thin film transistors).
Flexible resistors & capacitors structures are shown diagrammatically usually called
thin flim resistors and thin flim capacitors
