“…The most popular piezoelectric materials used in e-skin sensors, energy harvesters, and other types of sensors are lead zirconate titanate (PZT) [ 89 , 90 , 91 ], zinc oxide (ZnO) [ 68 , 87 , 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 , 100 , 101 ], barium titanate (BaTiO 3 ) [ 102 , 103 ], poly(vinylidene difluoride) (PVDF) and its co-polymers like poly[(vinylidenefluoride-co-trifluoroethylene] [P(VDF-TrFE)] and poly(vinylidene fluoride-co-hexafluoropropene) [P(VDF-HFP)] [ 88 , 99 , 102 , 103 , 104 , 105 , 106 , 107 , 108 ], and their piezoelectric coefficient, d 33 , can be found in Table 1 . The relation between the d 33 and the output of a piezoelectric sensor can be established by Equation (2):

where V is the voltage produced by the sensor, C is the capacitance, and F is the force applied to the sensor [ 109 ].…”

“…PZT and ZnO are commonly integrated into sensors in the form of thin films or nano/micro-structures to minimize their brittle nature [ 54 , 87 , 89 , 91 , 97 , 100 ]. PVDF polymers are highly flexible, yet require a poling process to maximize their typically low d 33 constant [ 54 , 99 , 102 , 103 , 105 , 106 , 107 , 108 ].…”

Electronic skin (e-skin), which is an electronic surrogate of human skin, aims to recreate the multifunctionality of skin by using sensing units to detect multiple stimuli, while keeping key features of skin such as low thickness, stretchability, flexibility, and conformability. One of the most important stimuli to be detected is pressure due to its relevance in a plethora of applications, from health monitoring to functional prosthesis, robotics, and human-machine-interfaces (HMI). The performance of these e-skin pressure sensors is tailored, typically through micro-structuring techniques (such as photolithography, unconventional molds, incorporation of naturally micro-structured materials, laser engraving, amongst others) to achieve high sensitivities (commonly above 1 kPa−1), which is mostly relevant for health monitoring applications, or to extend the linearity of the behavior over a larger pressure range (from few Pa to 100 kPa), an important feature for functional prosthesis. Hence, this review intends to give a generalized view over the most relevant highlights in the development and micro-structuring of e-skin pressure sensors, while contributing to update the field with the most recent research. A special emphasis is devoted to the most employed pressure transduction mechanisms, namely capacitance, piezoelectricity, piezoresistivity, and triboelectricity, as well as to materials and novel techniques more recently explored to innovate the field and bring it a step closer to general adoption by society.

Nanofibers/nanowires usually exhibit exceptionally low flexural rigidities and remarkable tolerance against mechanical bending, showing superior advantages in flexible electronics applications. Electrospinning is regarded as a powerful process for this 1D nanostructure; however, it can only be able to produce chaotic fibers that are incompatible with the well-patterned microstructures in flexible electronics. Electro-hydrodynamic (EHD) direct-writing technology enables large-scale deposition of highly aligned nanofibers in an additive, noncontact, real-time adjustment, and individual control manner on rigid or flexible, planar or curved substrates, making it rather attractive in the fabrication of flexible electronics. In this Review, the ground-breaking research progress in the field of EHD direct-writing technology is summarized, including a brief chronology of EHD direct-writing techniques, basic principles and alignment strategies, and applications in flexible electronics. Finally, future prospects are suggested to advance flexible electronics based on orderly arranged EHD direct-written fibers. This technology overcomes the limitations of the resolution of fabrication and viscosity of ink of conventional inkjet printing, and represents major advances in manufacturing of flexible electronics.

“…The advantage for PZT nanowire single crystal is possibly transferred onto flexible substrates, highly elastic and resistant to fatigue, and largely enhanced energy conversion efficiencies and piezoelectric constants because of the absence of domain boundaries which can pin up the dipole moments [112][113][114]. A flexible semitransparent energy harvesting with highly open voltage and stable power density of 10 V and 0.27 μW/cm 2 was fabricated in visible and near-infrared light regions, composed with laterally aligned Pb(Zr 0.52 Ti 0.48 )O 3 single nanowires and planar interdigitated Pt/Ti electrodes to avoid the decrease of dielectric constant from conventional sandwich configuration [115].…”

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.
