“…39 Technologically, such measurements could be valuable as Teflon substrates that exhibit micro-nanoscale surface roughness are being explored for energy harvesting with impinging water droplets. 40 In addition, the carbon working electrodes were functionalized with hydrous iridium oxide (IrOx) to create a pH responsive electrode 31 to follow the local pH change during the initial dissolution of a pristine calcite crystal surface. For this measurement, a functionalized quadprobe was filled with 10 mM KCl solution (pH 6.8) and brought into contact with a freshly cleaved calcite surface to form a thin layer electrochemical cell between the probe and crystal surface ( Figure 4C).…”

ABSTRACTThe fabrication and use of a multifunctional electrochemical probe incorporating two independent carbon working electrodes and two electrolyte-filled barrels, equipped with quasi-reference counter electrodes (QRCEs), in the end of a tapered micron-scale pipet is described. This 'quad-probe' (4-channel probe) was fabricated by depositing carbon pyrolytically into two diagonally opposite barrels of a laser-pulled quartz quadruple-barrelled pipet. After filling the open channels with electrolyte solution, a meniscus forms at the end of the probe and covers the two working electrodes. The two carbon electrodes can be used to drive local electrochemical reactions within the meniscus while a bias between the QRCEs in the electrolyte channels provides an ion conductance signal that is used to control and position the meniscus on a surface of interest. When brought into contact with a surface, localized high resolution amperometric imaging can be achieved with the two carbon working electrodes with a spatial resolution defined by the meniscus contact area. The substrate can be an insulating material or (semi)conductor, but herein we focus mainly on conducting substrates that can be connected as a third working electrode. Studies using both aqueous and ionic liquid electrolytes in the probe, together with gold and individual single walled carbon nanotube samples, demonstrate...

“…Structures are always obtained by the employment of a thin film of piezoelectric substrate encapsulated in an insulator shield. The first one is the cantilever structure, used in [9][10][11][12][13][14][15], in which the piezoelectric structure has one end bound while the other is free to move. Such structures allow a low damped movement as a result of the collision with the raindrops.…”

“…A recent work of Helseth [14] introduces different possibilities to harvest raindrop energy with piezoelectric and triboelectric transducers and evaluates the energy potential due to rain parameters. Lin et al [15] with a pioneering work suggested a recover energy of 30 nJ of electrical energy due to a droplet of 30 mL. These results leave some uncertainty on the actual capability to generate an adequate amount of electrical energy from rain.…”

Featured Application: With a view to reducing the employment of battery-powered systems to meet environmental requirements, sensors should be powered by energy harvesting systems. Sensors require little energy to perform measurements and also to transmit data; energy that can be recovered from rainwater by the harvesting structures.Abstract: In this paper, an experimental comparison between different rainfall harvesting devices through the study of the electrical rectifying circuit is proposed. In more detail, three harvesting structures are considered: the cantilever, the bridge and the floating circle. Different waveforms were acquired and discussed. The processed data were compared in order to suggest the best choice for the rectifying circuit, from the simplest one to that most frequently endorsed in the technical literature.

“…Fortunately, the low-cost, chemical stable, lightweight, small-sized, and high efficient triboelectric nanogenerators (TENGs), which can directly convert the mechanical energy in the environment to electric energy, can minimize the problem. [8][9][10][11][12] Herein we report a nanowire based TENG to collect the blue energy from ocean and its great potential for applications. First, the nanowire, which will largely add the roughness of surface and thus magnificently increase the contacting area of the FEP film and water, is fabricated by etching.…”

The ocean wave energy is one of the most promising renewable and clean energy sources for human life, which is the so-called “Blue energy.” In this work, a nanowire based triboelectric nanogenerator was designed for harvesting wave energy. The nanowires on the surface of FEP largely raise the contacting area with water and also make the polymer film hydrophobic. The output can reach 10 μA and 200 V. When combined with a capacitor, an infrared emitter, and a receiver, a self-powered wireless infrared system is fabricated, which can be used in the fields of communication and detecting.
