Inductor design for inkjet-printed electronics

摘要

This paper presents inductor design via ink-jet printing techniques for planar and multi-planar inductors while considering flexible substrates. These inductor designs can be adapted for use in high frequency filtering and power transfer in microelectronics. For these inductor designs, silver nanoparticle ink (Harima MPS-JL) was ink-jetted and cured on photo paper using a Dimatix DMP-2850 printer in order to construct spiral as well as meander printed inductors. The spiral inductor designs constructed consider both planar and multi-planar formats for both square and circular geometries whereas the meander inductor designs are strictly planar. The operational bandwidth of these inductors were limited to 10 MHz in order to compare design outputs such as quality factor, inductance and impedance. Subsequent testing, in order to demonstrate both high frequency filtering as well as power transfer, using auxiliary circuits was done.
