“…It is worth noting that with different polarization directions, PVDF can enhance or degrade the performance of TPNG as reported . Here, the surface‐potential coupling effect was simulated using COMSOL software to elucidate the electrical variation with different polarized directions of PVDF (Figure S3, Supporting Information).…”

Flexible biocompatible mechanical energy harvesters are drawing increasing interest because of their high energy‐harvesting efficiency for powering wearable/implantable devices. Here, a type of “self‐matched” tribo‐piezoelectric nanogenerators composed of genetically engineered recombinant spider silk protein and piezoelectric poly(vinylidene fluoride) (PVDF)‐decorated poly(ethylene terephthalate) (PET) layers is reported. The PET layer serves as a shared structure and electrification layer for both piezoelectric and triboelectric nanogenerators. Importantly, the PVDF generates a strong piezo‐potential that modifies the surface potential of the PET layer to match the electron‐transfer direction of the spider silk during triboelectrification. A “vapor‐induced phase‐separation” process is developed to enhance the piezoelectric performance in a facile and “green” roll‐to‐roll manufacturing fashion. The devices show exceptional output performance and energy transformation efficiency among currently existing energy harvesters of similar sizes and exhibit the potential for large‐scale fabrication and various implantable/wearable applications.

The advances in wearable/flexible electronics have triggered tremendous demands for flexible power sources, where flexible nanogenerators, capable of converting mechanical energy into electricity, demonstrate its great potential. Here, recent progress on flexible nanogenerators for mechanical energy harvesting toward self‐powered systems, including flexible piezoelectric and triboelectric nanogenerator, is reviewed. The emphasis is mainly on the basic working principle, the newly developed materials and structural design as well as associated typical applications for energy harvesting, sensing, and self‐powered systems. In addition, the progress of flexible hybrid nanogenerator in terms of its applications is also highlighted. Finally, the challenges and future perspectives toward flexible self‐powered systems are reviewed.

“…Although most self‐powered sensors achieve either high sensitivity or wide measurement range, they are hardly used for precise action identification . Hybrid piezoelectric–triboelectric sensors (HPTSs) have been proposed to further enhance the sensitivity and measurement range . For example, in Figure g, a piezoelectric–triboelectric sensor is composed of an ultraflexible nanopolarized microfrustum‐array PZT and PDMS film and an m‐Cu film.…”

The widespread implementation and rapid development of autonomous systems pose stringent performance requirements on emerging sensory systems. In addition to the basic sensing requirements, leading sensory systems are required to process data and extract featured information from highly redundant data in real time. With the added edge‐computational capabilities, data shuttling is avoided, leading to significant reduction of computational burden and bandwidth pressure in the cloud. Among the different computing architectures, the neuromorphic sensory system stands out due to its high power efficiency, low latency, and excellent processing capability. Mimicking the biological neural network, the colocation of sensory, processor, and memory components of neuromorphic sensory systems enables the requirements for frequent data shuttles to be circumvented. In particular, artificial intelligent perceptions built on memristive neuromorphic systems exhibit outstanding characteristics of small footprint, low power consumption, 3D stacking ability, and high density. Herein, the two essential parts of the memristive artificial perceptron system are presented: 1) memristive systems for neuromorphic computing and 2) high‐performance sensors. Next, the current state of the art established on artificial perceptron systems covering visual, auditory, and tactile sensations is highlighted. To conclude, the current challenges and future direction in the area of advanced intelligent perceptions are presented.
