Structure Design and Performance of Hybridized Nanogenerators

Intelligent energy generation from ambient environment by various nanogenerators is desirable to realize self‐powered operation of electronics. By integrating two or more kinds of nanogenerators, a hybridized nanogenerator provides a possible solution to largely increase the total electric power, and thus has been considered as one of the most significant energy‐related technologies. Here, emerging advancements in hybridized nanogenerators are summarized in terms of their structures, principles, and potential applications. In particular, one‐structure‐based coupled nanogenerators based on multifunctional energy‐scavenging materials and the interface regulation of solar cells by inner nanogenerators are discussed. For potential applications in wearable electronics, the new progress on flexible hybridized nanogenerators is presented on the basis of stretchable and mechanically durable materials, substrates, and electrodes. With the advances highlighted here and the ongoing research efforts, the continuous breakthrough in hybridized nanogenerators for multiple energy scavenging and their extensive applications is foreseeable in the future.
