“…[ 1,2 ] The conversion of mechanical energy into electrical energy using piezoelectric nanogenerators (PENGs) is one of the most important technologies for harvesting the energy of microscale ambient mechanical sources. [ 3–9 ] Among the various energy sources in nature, ambient actuation sources such as vibrations, bending, vehicle movement, air flow, fluid flow, muscle movement, running, and walking are the most abundant actuation sources for PENGs. [ 10–13 ] Conventionally, ceramics have been used to fabricate PENGs but they are not preferred for in vivo or in vitro applications because of their poor biocompatibility and flexibility.…”

Highly durable piezoelectric nanogenerators (PENGs) with high conversion efficiency and high power density are of great interest. Here, a foldable, scalable, durable, cost‐effective, sensitive, and high current output PENG developed by the direct integration of van der Waals heteroepitaxial growth of GaN nanowires (NWs) by metal‐organic chemical vapor deposition using a graphene coating on a Cu‐foil is reported where the direct growth of GaN on the metallic substrate plays a key role in achieving the high stability of the PENG. The PENG provides a durable and highly sensitive output compared to the previously reported GaN NW‐based PENGs fabricated by transferring NWs onto a foreign substrate. The reported PENG can harvest energy from a variety of ambient actuation sources such as bending, vibrations, air flow, finger pressing, foot striking, fluid flow, and normal force by weights, with the maximum piezoelectric output voltage and current density recorded as 19.7 V and 1.9 mA cm−2, respectively. Due to its high conversion efficiency, the PENG can power several LEDs and thus can be used to power electronic devices. More importantly, the PENG retains its performance after more than 4 million actuation cycles, demonstrating the potential of the design for practical applications using biomechanical and ambient actuation sources for self‐powered systems.

“…This kind of material can be divided in non-centrosymmetric crystal structure inorganic materials and in semi-crystalline polymeric materials. The former class includes ferroelectric materials such as lead titanate (PbTiO 3 ), lead zirconate titanate (PbZrTiO 3 ) ( Dagdeviren et al, 2014 , 2015 ) and modified lead zirconate titanate (PbZr x Ti 1−x O 3 ) ( Winestook et al., 2019 ), barium titanate (BaTiO 3 ) ( Guan et al., 2020 ), strontium bismuth titanate (SrBi 4 Ti 4 O 15 ), potassium sodium niobate ( Bairagi and Ali, 2020 ), and potassium niobate (KNbO 3 ) ( Yang et al., 2012 ). On the other hand, piezoelectric polymers for pressure/strain sensing consist of polypropylene ferroelectret (PPFE) ( Wu et al., 2015 ), where dipoles originate from electrically charged pores, and ferroelectric polymers such as polyvinylidene fluoride PVDF ( Chiu et al., 2013 ) and P(VDF-TrFE) ( Chen et al, 2015 ).…”

With the rapid development of the internet of things (IoT), sustainable self-powered wireless sensory systems and diverse wearable and implantable electronic devices have surged recently. Under such an opportunity, nanogenerators, which can convert continuous mechanical energy into usable electricity, have been regarded as one of the critical technologies for self-powered systems, based on the high sensitivity, flexibility, and biocompatibility of piezoelectric nanogenerators (PENGs) and triboelectric nanogenerators (TENGs). In this review, we have thoroughly analyzed the materials and structures of wearable and implantable PENGs and TENGs, aiming to make clear how to tailor a self-power system into specific applications. The advantages in TENG and PENG are taken to effectuate wearable and implantable human-oriented applications, such as self-charging power packages, physiological and kinematic monitoring, in vivo and in vitro healing, and electrical stimulation. This review comprehensively elucidates the recent advances and future outlook regarding the human body’s self-powered systems.
