“…Skin-mounted electronics have provided new routes for advanced wearable diagnostic/therapeutic solutions. [137][138][139][140][141][142][143][144][145][146] However, significant challenges still remain for the wearable displays that can show the monitored data from the wearable sensors to the user in real time. One of the major challenges for ideal wearability is the thickness and stiffness of the conventional flexible displays.…”

In the future electronics, all device components will be connected wirelessly to displays that serve as information input and/or output ports. There is a growing demand of flexible and wearable displays, therefore, for information input/output of the nextgeneration consumer electronics. Among many kinds of light-emitting devices for these next-generation displays, quantum dot light-emitting diodes (QLEDs) exhibit unique advantages, such as wide color gamut, high color purity, high brightness with low turn-on voltage, and ultrathin form factor. Here, we review the recent progress on flexible QLEDs for the next-generation displays. First, the recent technological advances in device structure engineering, quantum-dot synthesis, and high-resolution full-color patterning are summarized. Then, the various device applications based on cutting-edge quantum dot technologies are described, including flexible white QLEDs, wearable QLEDs, and flexible transparent QLEDs. Finally, we showcase the integration of flexible QLEDs with wearable sensors, micro-controllers, and wireless communication units for the next-generation wearable electronics.

The demand of flexible energy storage devices for portable and wearable electronics has become increasingly urgent due to the rapid development of microelectronic products, wearable devices, and smart skin. [1][2][3][4][5][6] Some of the most effective and practical technologies for electrochemical energy conversion and storage are batteries, fuel cells, and supercapacitors. [7][8][9][10][11][12][13][14][15] Among them, supercapacitors (SCs) have attracted intensive attentions due to their high power density and long lifecycle. [9,13,[16][17][18] The energy storage is performed by ion adsorption or fast surface redox reaction at the interface between electrodes and electrolyte. Moreover, all-solid-state microsupercapacitors (MSCs) can greatly facilitate the development The graphene with 3D porous network structure is directly laser-induced on polyimide sheets at room temperature in ambient environment by an inexpensive and one-step method, then transferred to silicon rubber substrate to obtain highly stretchable, transparent, and flexible electrode of the all-solidstate planar microsupercapacitors. The electrochemical capacitance properties of the graphene electrodes are further enhanced by nitrogen doping and with conductive poly(3,4-ethylenedioxythiophene) coating. With excellent flexibility, stretchability, and capacitance properties, the planar microsupercapacitors present a great potential in fashionable and comfortable designs for wearable electronics.
