Journal ArticleDOI
Drying-Mediated Self-Assembled Growth of Transition Metal Dichalcogenide Wires and their Heterostructures.
TL;DR: The acidity of the reaction media can effectively suppress the gradation of the precursor diffusion, which is the driving force in the generation of the dendrite side-arms and the lateral expansion of the selfassembly, thereby preserving the main stream and, as a result, enhancing the formation of aligned wire arrays.

Touch sensor using graphin for simultaneously detecting pressure and position
TL;DR: In this article, a touch sensor for measuring a touch position and the degree of touching pressure by using graphin as an electrode and/or a strain gauge is presented, and more particularly a touch sensors for simultaneously detecting pressure and position by means of change in resistance by using the graphin.
Journal ArticleDOI

TL;DR: It was found that the TX additive inhibits interface recombination between PEDot:PSS and MAPbI3, which is caused by the suppression of semimetallic properties of the PEDOT: PSS surface, and flexible PSCs were fabricated successfully using a graphene electrode and TX-modified PEDots.
Journal ArticleDOI
Si membrane based tactile sensor with active matrix circuitry for artificial skin applications
TL;DR: In this paper, the fabrication and the characteristics of an inorganic silicon-based flexible tactile sensor equipped with active-matrix circuitry compatible with a batch microfabrication process are reported.
Journal ArticleDOI
Additive-free synthesis of Li4Ti5O12 nanowire arrays on freestanding ultrathin graphite as a hybrid anode for flexible lithium ion batteries
TL;DR: Li4Ti5O12 (LTO) nanowire arrays were used in this paper to construct a high-power, lightweight, and flexible lithium-ion batteries (FLIBs) to fulfill the energy requirements of future flexible electronic devices.
