Upon touch from a ﬁnger, the single electrode-mode energy harvester generates up to 27.0 W/ Revised 29 December 2017 2 m output power at 10 MX matched impedance. The device generates stable power upon touch by bare Accepted 22 February 2018 ﬁngers or gloved ﬁngers. Using copper counter electrode results in decreased power output, due to the Available online 24 February 2018 weaker tendency in triboelectriﬁcation. The power output also scales with the pressure applied by the ﬁnger. The intertwined, condensed MWCNT network acts as a ﬂexible yet effective current collector, with
