In　recent　decades,　the　development　and　optimization　of　supercapacitors　have　garnered　a　great　deal　of　attention　for　the　reason　that　it　is　a　promising　method　to　store　energy　and　supply　power　to　the　wireless　sensors　and　portable　electronics.　Therefore,　carbon　nanotube　(CNT)　and　zinc　oxide　(ZnO)　based　supercapacitors　are　reported　in　this　paper　for　high-performance　energy　storage.　The　electrodes　with　different　contents　of　ZnO　and　CNT　are　obtained　by　orderly　depositing　carbon　nanofiber　(CNF),　ZnO　and　CNT　nano-materials　on　tissue　substrates　through　the　method　of　suction　filtration.　Fourier　transform　infrared　spectroscopy　(FTIR),　scanning　electron　microscopy　(SEM)　and　electrochemical　testing　are　carried　out　in　the　experiments　to　characterize　the　composition,　morphology　and　electrochemical　performance　of　the　electrodes.　Results　show　that　the　increase　in　the　content　of　CNT　will　enhance　capacitive　performance.　While　for　ZnO,　the　capacitive　performance　of　the　electrodes　will　firstly　increase　and　then　decrease　with　the　increase　of　the　content.　Furthermore,　the　largest　areal　capacitance　obtained　in　the　experiment　at　a　scan　rate　of　50　mV/s　is　14.6　mF/cm2.　Finally,　the　sensing　ability　of　the　electrode　is　demonstrated　by　output　voltage　under　finger　tapping　testing　due　to　the　piezoelectricity　of　ZnO.　©　2020　Elsevier　Ltd
