Flexible and Transparent Nanogenerators Based on a Composite of Lead‐Free ZnSnO₃ Triangular‐Belts

Abstract

A flexible and transparent lead-free triangular-belt ZnSnO(3) nanogenerator is demonstrated. When a mechanical deformation of ≈0.1% is applied to the triangular-belt ZnSnO(3) nanogenerator, the output voltage and current reached 5.3 V and 0.13 μA, respectively, which indicated a maximum output power density of ≈11 μW·cm(-3). This is the highest output power that has been demonstrated by lead-free ZnSnO(3) triangular-belts.

Vertically stacked thin triboelectric nanogenerator for wind energy harvesting

“…As mobile electronic devices and wireless sensors have dramatically advanced recently, the importance of small-size energy harvesters is rapidly increasing [1][2][3][4][5][6][7][8]. Power requirements of such mobile devices are small enough that they can be operated with a battery, but the unavoidable recharging and replacement process is a critical limitation.…”

High sensitivity wrist-worn pulse active sensor made from tellurium dioxide microwires

“…When an external force was applied in the [0001] direction, the crystal domains created a significant piezopotential along with the [0001]. In addition to the wurtzite structure, the highly powered-output nanogenerators made from ferroelectric materials, such as ZnSnO 3 [19][20][21], BaTiO 3 [22], NaNbO 3 [23], and Pb(Zr,Ti)O 3 [24], becomes more noticeable for the application in energy harvesting devices. However, there is no net piezopotential output unless the random ferroelectric crystal domains are poled by applying a direct current voltage across the ferroelectric material.…”

Energy harvesting from nanofibers of hybrid organic ferroelectric dabcoHReO4

“…[1][2][3] The development of smart textiles is also an emerging research field having promising multiple impacts on various technological applications including wearable electronics, implantable physiological sensing and monitoring, signal and power pathways, large surface lighting or heating, and electromagnetic shielding or textile antennas. [4][5][6] The common approach to design functional fabric for wearable devices consists of attaching conventional off-shelf micro-electronic components such as transducers, light emitting diodes, and microcomputers to the clothes.…”

“…The bands at 1007 cm 1 and 930 cm 1 correspond, to symmetric and antisymmetric stretching vibrations of C C bonds respectively and characterize the orientation of the dipole moment of the dabco molecule. 25,26 The presence of a 1007 cm 1 line in the spectrum of nanofibers indicates that dabco molecules are mainly oriented in the plane of the mat, whereas its angular independence shows the deviation of molecules from the fiber's axis at a certain angle.…”

“…25,26 The presence of a 1007 cm 1 line in the spectrum of nanofibers indicates that dabco molecules are mainly oriented in the plane of the mat, whereas its angular independence shows the deviation of molecules from the fiber's axis at a certain angle. An average value of this angle was found from analysis of intensity of several A 1 Raman bands including lines at 803 and 1007 cm 1 . Considering the Raman polarizability tensor, 27 we found that dabco molecules are in the bc-plane and are rotated along Z-axis with average angle of 23 .…”
