Paper electronics using solution processing is rapidly evolving and the possibility of extending the available information beyond the printed graphic is very interesting . However, paper imposes special requirements for manufacturing electronic components by being rough and absorptive, the need for recyclability and/or compostability. For paper electronics to be truly recyclable and/or disposable the components need be environmentally friendly and bio-compatible, and preferably operating at low voltages. Here we propose an environmentally safe approach to such active circuits and electronic functionalities, by making ion-modulated transistors (IMTs) on paper .
We have further developed the paper electronics platform towards a fully printable paper-based test array for material-cell interaction studies . The paper-based cell growth platform has been shown to provide an efficient and excellent high-throughput and low-cost platform for studying the effect of materials and surfaces on cell functions.
