We present a hybrid electromagnetic generator (EMG) and leaf-shaped polytetrafluoroethylene (PTFE) triboelectric nanogenerator (TENG) with an arc-shaped brace structure for mechanical energy harvesting. The pick-up coil is incorporated into a carbon black (CB) and silicone rubber mixture film at the bottom of the separation component as the EMG, and the TENG is carefully designed with two opposite arc-shaped braces for the contact and separation. It has been demonstrated that the leaf-shaped PTFE film could greatly enhance the collection efficiency of the mechanical energy due to both the leaf-shaped surface and the high voltage corona charge in the TENG. The EMG and TENG can achieve an instantaneous power output of 80 mu W cm(-2) and 675 mu W cm(-2) by calculation, respectively. Moreover, a random finger tap test revealed that a high electrical performance is achieved, with a voltage output of 0.25 V and 24 V from the EMG and TENG, respectively.
