High-response humidity sensing with graphene oxide/lignosulfonate and laser-induced graphene for respiratory health.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Most current commercial humidity sensors rely on precious metals and chemicals. In this study, alkali lignin produced in the paper industry was utilized to form a film with hydroxyethyl cellulose to generate laser-induced graphene (LIG) as an electrode material for a sensor by the laser-induction technique. LIG exhibits excellent conductivity, and the experimental results demonstrate that its resistivity can be adjusted by laser power without the necessity for additional conductive materials. A solution comprising a blend of graphene oxide and sodium lignosulfonate was introduced to the LIG surface in a dropwise manner, thereby establishing a sensing surface. This process resulted in the introduction of hydrophilic groups, including carboxyl, phenolic hydroxyl, and sulfonic acid. The integration of these hydrophilic groups enhanced the surface's sensitivity to humidity, thereby facilitating the precise capture of alterations in ambient air humidity. The humidity sensor, which employs alkali lignin and lignin laser-induced graphene as electrodes and graphene oxide (GO) as the humidity-sensitive layer, exhibits an exceptionally high degree of sensitivity to humidity.
