A stretchable flexible electronic platform for mechanical and electrical collaborative design

Abstract

With the extensive application of stretchable flexible electronic circuits to wearable equipment and biomedicine, research on the electrical properties of such circuits has become a hot topic. In this paper, a flexible electronic design platform is established for the first time, realizing co-simulation of the mechanical and electronic aspects. The main functions of this platform include the design of stretchable interconnects, flexible devices, stretchable flexible electronic circuits, and stretchable flexible circuit-layout wiring. The following conclusions can be obtained: (1) With increased applied strain, the inductance of a stretchable interconnect will increase, while the delay and crosstalk will become non-negligible. (2) Although the performance of flexible passive devices does not change after transfer printing, the gate capacitor of the flexible MOS at the cut-off area does decrease. (3) Taking a flexible comparator as an example, the function and electrical performance of a flexible circuit are verified. (4) Taking a flexible amplifier circuit as an example, the flexible interconnection layout and wiring are simulated and verified.
