CNF–HEC纳米纤维素复合电子基底 / 纤维素电子皮肤

CNF–HEC Nanocellulose Composite Substrate / Cellulose e-skin

A biodegradable CNF–HEC nanocellulose composite substrate developed by VTT for recyclable flexible printed electronics. In the ECG patch demonstrator, the single-use skin-contact patch is made from nanocellulose and printed with carbon ink conductors and ECG sensing electrodes. The electronic module is removable and reusable, making the case valuable as both a bio-based material application and a modular end-of-life design strategy.
