“…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.…”

“…Piezo supercapacitors are emergent technologies which can harness and store energy at the same time from a natural process such as breathing, walking, arm movements, etc. making them attractive for biomedical devices due to their ability to generate power (Chodankar et al, 2021).…”

“…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.…”
