“…Therefore, piezoelectric sensors integrated with energy storage systems are extremely beneficial for their practical application. As shown in Figure 4 a [ 83 ], coupling piezoelectric materials into supercapacitors to form piezoelectric supercapacitors (PSCs) can not only harvest and store energy, but also realize pressure monitoring. The polarization charge generated by piezoelectric material produces potential difference between the positive and negative electrodes, driving the anions and cations in the electrolyte to move to a new balance, which is similar to the charging process of a supercapacitor, so as to realize energy storage.…”

“…The maximum charging voltage was positively correlated with pressure and frequency ( Figure 4 e(ii,iii)). This type of energy harvest-storage system based on the piezoelectric effect has been widely studied [ 83 ]. Although most of them can realize sensing, energy harvest, and storage, their sensing performance (sensitivity, detection range and limit, response time) is relatively low compared to traditional piezoelectric pressure sensors.…”

With the rapid prosperity of the Internet of things, intelligent human–machine interaction and health monitoring are becoming the focus of attention. Wireless sensing systems, especially self-powered sensing systems that can work continuously and sustainably for a long time without an external power supply have been successfully explored and developed. Yet, the system integrated by energy-harvester needs to be exposed to a specific energy source to drive the work, which provides limited application scenarios, low stability, and poor continuity. Integrating the energy storage unit and sensing unit into a single system may provide efficient ways to solve these above problems, promoting potential applications in portable and wearable electronics. In this review, we focus on recent advances in energy-storage-device-integrated sensing systems for wearable electronics, including tactile sensors, temperature sensors, chemical and biological sensors, and multifunctional sensing systems, because of their universal utilization in the next generation of smart personal electronics. Finally, the future perspectives of energy-storage-device-integrated sensing systems are discussed.

Biomedical implantable devices like deep brain stimulators, implantable cardioverter-defibrillators and cardiac pacemakers are essential for treating the human heart and brain-related diseases. In the past few decades, a considerable amount of research has focused on improving bio-implant technologies. Conventional bio implant devices consist of an external generator like a battery to power the system, which requires replacement after a particular time. Therefore, in recent years, self-powered implants with various energy harvesting techniques have been proposed to avoid frequent surgery for battery replacement and to miniaturise the implant systems. However, the research communities have yet to explore all the limitations and possibilities of improvement on such energy-scavenging technologies, especially when the application is in vivo. Several aspects of recent developments in energy harvesting technologies feasible for biomedical implantable devices are reported systematically. A detailed review of piezoelectric energy harvester mechanism and miniaturisation, electric output and power management and biocompatibility of an energy harvester for implantable medical devices in vitro and in vivo environments. Furthermore, the piezoelectric energy harvester’s durability, packaging material, connection and evaluation criteria are discussed.

“…In response to the increasing global demand for energy and the dwindling fossil resources, scientists have developed a variety of devices that can independently harvest energy, 93 such as piezoelectric nanogenerators (PENGs), friction nanogenerators (TENGs), and solar cells. These devices provide an efficient way for the continuous power supply of flexible supercapacitors.…”
