With the rapid development of the Internet of things (IoT), flexible piezoelectric nanogenerators (PENG) have attracted extensive attention for harvesting environmental mechanical energy to power electronics and nanosystems. Herein, porous piezoelectric fillers with samarium/titanium-doped BiFeO 3 (BFO) are prepared by a freeze-drying method, and then silicone rubber is filled into the microvoids of the piezoelectric ceramics, forming a unique structure based on silicone rubber matrix with uniformly distributed piezoelectric ceramic. When subjected to external force stimulation, compared with conventional piezocomposite films found on undoped BFO without a porous structure, the PENG possesses higher stress transfer ability and thus boosts output performance. The notable enhancement in the stress transfer ability and piezoelectric potential is proven by COMSOL simulations. The PENG can exhibit a maximum open-circuit voltage (V oc ) of 16 V and shortcircuit current (I sc ) of 2.8 µA, which is 5.3 and 5.6 times higher than those of conventional piezocomposite films, respectively. The PENG can be used as a triggering signal to control the operation of fire extinguishers and household appliances. This work not only expands the application scope of lead-free piezoelectric ceramic for energy harvesting, but also provides a novel solution for self-powered mechanosensation and shows great potential application in IoT.

lithium-ion batteries, such as low life, serious pollution, and low safety, have always plagued the development of intelligent wearable devices and intelligent devices. If the energy module of smart wearable devices explodes, the apparent harm is conceivable. [10][11][12] Therefore, the development of a safe and lightweight energy source is urgently necessary. Given the rapid development of the integrated circuits (IC) and low power sensors, the power requirement of smart wearable electronic devices has been reduced from mW to µW. [13][14][15] To solve this problem, it is feasible and effective to collect body movement energy and convert it into electric energy to supply power for smart wearable devices. [16,17] Presently, many kinds of equipment designed to collect body energy have been reported. [18][19][20][21] This study is divided into electromagnetic generator, friction generator, and composite generator. The friction generator provides energy for external electrical appliances under the principle of friction charge effect and electrostatic balance effect, where the relative position change of different electronegative materials will produce the change of electric potential. [22] The electromagnetic generator generates power through the induction of current by the change of magnetic field in closed coil. The composite generator is an effective combination of these two kinds of generator. The friction nanogenerator is obviously more suitable to supply power for intelligent wearable equipment because of its safety and lightweight compared with magnetoelectricity and composite generator. The main direction of this research is to improve the output performance of the proposed nanogenerator. This can be achieved by changing the characteristics of materials through mixing, microprocessing, and other methods. [23][24][25][26] Another method is to improve the collection efficiency of environmental energy by changing the structure of devices.Nature has rich scientific principles such as DNA, which is tightly and steadily aligned with base pairs containing genetic information in the form of helical twists. The combination of the corresponding base pairs can form an effective genetic expression. This allows the arrangement of more genetic information and match more genetic information accurately in a smaller space in the nucleus. It guarantees the richness and security of information. The relative friction layer and electrode Collecting energy from body movements to supply power for equipment is an important method to rapidly develop wearable intelligent equipment. This method places high requirements, such as being lightweight and stable, on a nanogenerator. Herein, a bioinspired helical triboelectric nanogenerator (BH-TENG) that realizes energy acquisition through the intensity and frequency of body movement is designed based on the helical structure of DNA. The helical structure facilitates more contact areas and provides increased stability to complete the power generation process than the simple structure with pl...

Thin, soft, skin‐like electronics capable of transforming body mechanical motions to electrical signals have broad potential applications in biosensing and energy harvesting. Forming piezoelectric materials into flexible and stretchable formats and integrating with soft substrate would be a considerable strategy for this aspect. Here, a skin‐integrated rubbery electronic device that associates with a simple low‐cost fabrication method for a ternary piezoelectric rubber composite of graphene, lead zirconate tinanate (PZT), and polydimethylsiloxane (PDMS) is introduced. Comparing to the binary composite that blend with PZT and PDMS, the graphene‐embedded ternary composite exhibits a significant enhancement of self‐powered behavior, with a maximum power density of 972.43 µW cm−3 under human walking. Combined experimental and theoretical studies of the graphene‐embedded PZT rubber allow the skin‐integrated electronic device to exhibit excellent mechanical tolerance to bending, stretching, and twisting for thousands of cycles. Customized device geometries guided by optimized mechanical design enable a more comprehensive integration of the rubbery electronics with the human body. For instance, annulus‐shape devices can perfectly mount on the joints and ensure great power output and stability under continuous and large deformations. This work demonstrates the potential of large‐area, skin‐integrated, self‐powered electronics for energy harvesting as well as human health related mechanical sensing.
