3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

open access: yesAdvanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.

Raman fiber laser with highly non-linear fiber [PDF]

open access: yes2014 IEEE 5th International Conference on Photonics (ICP), 2014
This paper demonstrates the power performance of an asymmetrical distributed feedback Raman fiber laser (DF-RFL) employing 2 km of highly nonlinear fiber (HNLF). The forward-pumped architecture exhibited better threshold condition and higher output power alongside a broader spectral profile compared to a DF-RFL utilizing a standard transmission fiber ...
