flexible and robust laser-induced graphene heaters

A Review of Printable Flexible and Stretchable Tactile

Flexible and stretchable tactile sensors that are printable, nonplanar, and dynamically morphing are emerging to enable proprioceptive interactions with the unstructured surrounding environment. Owing to its varied range of applications in the field of wearable electronics, soft robotics, human-machine interaction, and biomedical devices, it is required of these sensors to be flexible and

2017/5/17 Gas can turn laser-induced graphene superhydrophilic or Gas can turn laser-induced graphene superhydrophilic or superhydrophobic Researchers at Rice University, who invented laser-induced graphene (LIG), in collaboration with researchers at Ben-Gurion University in Israel, have designed a way to make the spongy graphene either superhydrophobic or superhydrophilic.

In situ MoS2 Decoration of Laser

Herein, we are reporting a rapid one-pot synthesis of MoS2-decorated laser-induced graphene (MoS2-LIG) by direct writing of polyimide foils. By covering the polymer surface with a layer of MoS2 dispersion before processing, it is possible to obtain an in situ decoration of a porous graphene network during laser writing. The resulting material is a three-dimensional arrangement of agglomerated
