Abstract
An electronic component such as a voltage controllable reconfigurable capacitor or transistor is formed by printing one or more layers of ink on a non-conductive substrate. Ferroelectric ink or semi-conductive ink is printed and conductive resistive or dielectric ink is printed on a s same or different layers. Reconfigurability is achieved by printing resistive biasing circuitry wherein when a changing voltage is applied to the biasing circuitry, an electronic property of the electronic component changes in response to the changing voltage.
