“…Recently, the triboelectric nanogenerator (TENG), an energy collection device that can convert mechanical energy in the ambient environment into electricity by coupling triboelectrification and electrostatic induction effects, has been widely applied in energy harvesting, self-powered sensing systems, wearable devices, and so on. − Given that numerous mechanical energies in the environment are irregular and random, it becomes difficult for TENG with rigid tribo layers or electrodes to efficiently harness them. − On the one hand, these types of TENG usually gather mechanical energy in one specific motion direction, and hence, any change in the motion direction would cause unsatisfactory contact between the tribo materials, leading to a decrease in the output performance of TENG. , On the other hand, rigid materials are undeformable, and hence they are incompatible with soft and biological systems, limiting the application of TENG in areas such as human motion monitoring, wearable devices, etc. − Thus, elastic materials and a flexible structure design have drawn the attention of researchers and have been applied in TENG. These kinds of TENGs, with a flexible structure or composed of soft and elastic materials, can act as tribo materials or electrodes, can harvest random and irregular energies, and have great potential application value in fields such as self-powered wearable devices, human motion monitoring, and so on. − …”

Elastic sponges are ideal materials for triboelectric nanogenerators (TENGs) to harvest irregular and random mechanical energy from the environment. However, the conductive design of the elastic materials in TENGs often limits its applications. In this work, we have demonstrated that an elastic conductive sponge can be used as the triboelectric layer and electrode for TENGs. Such an elastic conductive sponge is prepared by a simple way of adsorbing multiwalled carbon nanotubes and monomers of pyrrole to grow conductive polypyrroles on the surface of an elastic polyurethane (PU) sponge. Due to the porous structure of the PU sponge and the conductive multiwalled carbon nanotubes (MWCNTs), PPy on the surface of PU could provide a large contact area to improve the output performance of TENGs, and the conductive sponge-based TENG could generate an output of open-circuit voltage of 110 V or a short-circuit current of 12 μA, respectively. The good flexibility of the conductive PU sponge makes the TENG harvest the kinetic energy of disordered motion with different amplitudes, allowing for human motion monitoring. Furthermore, the porous structure of PU and the synergistic effects of PPy and MWCNTs enable the conductive sponge to sense NH 3 as a self-powered NH 3 sensor. This work offers a simple way to construct a flexible TENG system for random mechanical energy harvesting, human motion monitoring, and self-powered NH 3 sensing.
