Phys.org:

The team designed a large-area active-matrix OLED (AMOLED) display with an MoS2 backplane via a sequence of processes. They first formed a thin-film-transistor (TFT) array on a thin MoS2 film, then deposited an RGB OLED on the drain electrode of the TFTs and peeled the display from the carrier to transfer it to the human hand (the target). During the process, they synthesized a bilayer MoS2 film on a 4-inch SiO2/Si wafer via metal organic chemical vapor deposition (MOCVD). Then they coated a polyethylene terephthalate (PET) substrate with aluminium oxide using atomic layer deposition and transferred the MoS2 film from the SiO2/Si wafer to this PET substrate to produce an MoS2 transistor array with a driving backplane configuration. The resulting structure was unique and encapsulated with aluminium oxide for improved metal contacts and carrier mobility. The full-color AMOLED display uniformly controlled the RGB OLED pixels, where each pixel connected to a data and a scanning line and the entire display circuit functioned in an active-matrix design. Choi et al. controlled the pixel current based on the drain and gate signals of the transistor to change the brightness of the OLED. They could then transform the ultrathin display from the carrier glass substrate to a curved surface without device degradation.

Chameleon skin, coming soon.

      If one stays at home playing video games in mom's basement, is deodorant actually necessary?

      But Mooooooooom! I've already been social distancing for years!

    Who would willingly put toxic things like aluminum oxides on their skin?

    Side effects:

    Rev 16:2, 10-11 [biblegateway.com]
    The first angel went and poured out his bowl on the land, and ugly, festering sores broke out on the people who had the mark of the beast and worshiped its image.

    10 The fifth angel poured out his bowl on the throne of the beast, and its kingdom was plunged into darkness. People gnawed their tongues in agony 11 and cursed the God of heaven because of their pains and their sores, but they refused to repent of what they had done.

    Consequences:

    Rev 14:9-12 [biblegateway.com]
    9 A third angel followed them and said in a loud voice: “If anyone worships the beast and its image and receives its mark on their forehead or on their hand, 10 they, too, will drink the wine of God’s fury, which has been poured full strength into the cup of his wrath. They will be tormented with burning sulfur in the presence of the holy angels and of the Lamb. 11 And the smoke of their torment will rise for ever and ever. There will be no rest day or night for those who worship the beast and its image, or for anyone who receives the mark of its name.” 12 This calls for patient endurance on the part of the people of God who keep his commands and remain faithful to Jesus.
