The researchers — who are based at Nanjing Forestry University, the Nanjing University of Science and Technology, the Northeast Forestry University, South China Agricultural University and Scion — used a transparent wood film substrate and a conductive cellulose-based ink to fabricate flexible electronics that can be bent, folded and rolled. To make the transparent substrate, a delignification process was applied to balsa wood that removes most of the lignin from the cell walls while keeping the original honeycomb structure. The conductive ink was a mix of oxidized cellulose nanofibres and carbon nanotubes.

The team used origami principles to transform two-dimensional sheets into three-dimensional structures. A proof-of-principle motion sensor was also created that switches on and off depending on the folding states.

这些研究人员来自南京林业大学、南京理工大学、东北林业大学、华南农业大学和 Scion，他们使用透明木膜基材和导电纤维素基油墨制造了可以弯曲、折叠和滚动的柔性电子产品。为了制造透明基材，对轻木进行了脱木素处理，从细胞壁中去除了大部分木质素，同时保持了原始的蜂窝结构。导电油墨是氧化纤维素纳米纤维和碳纳米管的混合物。

该团队使用折纸原理将二维片材转化为三维结构。此外，还创建了一个原理验证运动传感器，可根据折叠状态打开和关闭。
