“…Piezoelectric materials generate electricity in response to a pressure signal; most common among them is the highperforming but brittle piezoelectric material lead zirconate titanate (PZT). [ 188 ] Flexible piezoelectric nanogenerators have recently been developed based on more fl exible forms of PZT such as thin ribbons [ 189 ] or nanowires, [ 190 ] as well as lead-free materials such as PVDF, [ 145,165,[191][192][193] ZnO nanowires, [ 194 ] and cellular polypropylene. [ 75 ] Triboelectric generators, on the other hand, generate electricity from the transfer of surface charge that occurs when certain materials, including many common metals and polymers, are brought into contact, [ 144 ] either by pressing and releasing [ 195 ] or sliding.…”

Advances in wireless technologies, low-power electronics, the internet of things, and in the domain of connected health are driving innovations in wearable medical devices at a tremendous pace. Wearable sensor systems composed of flexible and stretchable materials have the potential to better interface to the human skin, whereas silicon-based electronics are extremely efficient in sensor data processing and transmission. Therefore, flexible and stretchable sensors combined with low-power silicon-based electronics are a viable and efficient approach for medical monitoring. Flexible medical devices designed for monitoring human vital signs, such as body temperature, heart rate, respiration rate, blood pressure, pulse oxygenation, and blood glucose have applications in both fitness monitoring and medical diagnostics. As a review of the latest development in flexible and wearable human vitals sensors, the essential components required for vitals sensors are outlined and discussed here, including the reported sensor systems, sensing mechanisms, sensor fabrication, power, and data processing requirements.

“…[7][8] Among them, fluorine-based polymer such as poly(vinylidene fluoride) (PVDF) [9][10][11] , poly(vinylidene fluoride-co-trifluoroethylene) (PVDF-TrFE) [12][13] and poly(vinylidene fluoride-co-trifluoroethlyene-co-chlorotrifluoro ethylene) (PVDF-TrFE-CTFE) 14 , have attracted great interest as flexible piezoelectric materials because they are strongly polarized under pressure due to the negatively charged fluorine atoms and positively charged hydrogen atoms in the chain backbones of these polymers. The piezoelectric output responses of these piezoelectric fluorine-based polymers have been developed by crystal orientation control 15 , blending with inorganic piezoelectric materials and conductive carbon 16 , and electrospinning fiber alignment. 17 Although the development and attention for piezoelectric fluorine-based polymers, the most serious drawback is the formation of toxic gases such as hydrogen fluoride (HF) during degradation or heating process.…”

With the rapid development of advanced technology, piezoelectric energy harvesting (PEH) with the advantage of simple structure, polluted relatively free, easily minimization, and integration has been used to collect the extensive mechanical energy in our living environment holding great promise to power the self-sustainable system and portable electronics. In this paper, attempts have been made to review the progress of piezoelectric materials and devices used for energy harvesting. The review focused on three parts: structure of piezoelectric devices (cantilever, cymbal, and stacks); theoretical mode, including vibration mode (d 31 and d 33 ) and its responding theories of different devices; and piezoelectric materials, among which the electric performance of Pb(ZrTi)O 3 -based, lead-free-based, and composites applied in bulk/micro/nano-PEH devices were introduced in details. It is suggested that a new structure of PEH should be designed by combining advantages of cantilever, stacks, and cymbal structure. Besides, high d 33 × g 33 value and low ε of piezoelectric materials are required in order to generate high electric output power for bulk/micro/nano-PEH. Additionally, lead-free piezoelectric ceramics is a candidate for manufacturing PEH devices, and nano-composite materials should be developed to further improve the flexibility of piezoelectric materials.
