Technological impact of functional materials. A number of microelectronic and telecommunication devices involve (a) an accelerometer that converts mechanical constraints into an electrical signal (Adapted with permission from ref. 209, Copyright American Chemical Society 2017), b an electrochemical cell whose electron-blocking electrolyte helps convert the flow of ions into electricity (Adapted with permission from ref. 210, Copyright American Chemical Society 2012) c a liquid crystal display that modulates the polarization of light as a function of the external voltage (Adapted with permission from ref. 211, Copyright American Chemical Society 2017) and d light-emitting diodes that are coated with phosphor layers modifying the color of the emitted light (Adapted with permission from ref. 212, Copyright American Chemical Society 2016)
