	abstract = {<p>A healable transparent capacitive touch screen sensor has been fabricated based on a healable silver nanowire{\textendash}polymer composite electrode. The composite electrode features a layer of silver nanowire percolation network embedded into the surface layer of a polymer substrate comprising an ultrathin soldering polymer layer to confine the nanowires to the surface of a healable Diels{\textendash}Alder cycloaddition copolymer and to attain low contact resistance between the nanowires. The composite electrode has a figure-of-merit sheet resistance of 18 Ω/sq with 80\% transmittance at 550 nm. A surface crack cut on the conductive surface with 18 Ω is healed by heating at 100 {\textdegree}C, and the sheet resistance recovers to 21 Ω in 6 min. A healable touch screen sensor with an array of 8 {\texttimes} 8 capacitive sensing points is prepared by stacking two composite films patterned with 8 rows and 8 columns of coupling electrodes at 90{\textdegree} angle. After deliberate damage, the coupling electrodes recover touch sensing function upon heating at 80 {\textdegree}C for 30 s. A capacitive touch screen based on Arduino is demonstrated capable of performing quick recovery from malfunction caused by a razor blade cutting. After four cycles of cutting and healing, the sensor array remains functional.</p>},
