“…27 Unlike the PE EH, the ES variant is able to operate without smart materials; it thus places less concern on the system life span. 28 Lee et al 29 have compared the contact surfaces of such designs and found that performance increases with the scale of roughness, 29 as displayed in Figure 6. 17 The output voltage is extremely high (usually over 100 V); hence, this approach is less compatible with MEMS or WSN.…”

“…17 An ES design 26 with less material and lower cost uses 2 dissimilar polymer sheets without an interlayer-binding sandwiched structure. 28 Lee et al 29 have compared the contact surfaces of such designs and found that performance increases with the scale of roughness, 29 as displayed in Figure 6. In another similar experiment, a VEH achieved 30 a top voltage of 34.06 V and a peak output power density of 0.77 W/m 2 .…”

Summary Energy harvesting technologies are growing rapidly in recent years because of limitation by energy storage and wired power supply. Vibration energy is abundant in the atmosphere and has the potential to be harvested by different mechanisms, mainly through piezoelectric and electromagnetic means. Various architectural structures were also designed for several operating conditions, namely, resonance frequency and range thereof, acceleration, and energy extraction from several motions. The advantages and disadvantages were elaborated on, and improvements on ideas from current research were discussed in this review.

“…To achieve silicon powder (in the form of porous substrate), the obtained product was washed with distilled water until the neutral pH was achieved and subsequently dried for about 24 hours at room temperature. The simple mechanism in the metalassisted chemical etching process is described with the help of the following half-reactions [22][23][24]:…”

A bismuth@porous silicon (Bi/PSi) nanostructure is fabricated and used as a new highly sensitive electrochemical sensor for measurement of thioridazine. For this purpose, commercial silicon powder is converted to porous silicon using metal‐assisted chemical etching method. Then, bismuth nanoparticles are deposited on the surface of the porous silicon that synthesized in the previous step. The effects of pH and instrumental parameters are studied on the sensor response. After optimization of the parameters, differential pulse voltammetry is used to determine sub‐micro molar amounts of thioridazine. The Linear region of the electrochemical sensor is in the range of 0.1 to 260 μmol L−1 thioridazine with a detection limit of 0.03 μmol L−1, when Bi/PSi/CNTPE is used as an electrochemical sensor. The precision and accuracy of the sensor is evaluated. The Bi/PSi/CNTPE is used as an appropriated tool for accurate measurement of low amounts of thioridazine in real samples with satisfactory results.

“…To achieve record-high energy harvesting performance in the triboelectric devices, the electrified surface charges after the mechanical input should be enhanced using various physical or chemical approaches. In the early stages of triboelectric device research, the random surface morphologies were applied to the devices using intrinsic roughness or plasma etching, to name a few [3,88,89]. However, they presented serious demerits such as morphological limitation, poor controllability, unavailable materials, and so on.…”

Mechanical energy harvesting technology converting mechanical energy wasted in our surroundings to electrical energy has been regarded as one of the critical technologies for self-powered sensor network and Internet of Things (IoT). Although triboelectric energy harvesters based on contact electrification have attracted considerable attention due to their various advantages compared to other technologies, a further improvement of the output performance is still required for practical applications in next-generation IoT devices. In recent years, numerous studies have been carried out to enhance the output power of triboelectric energy harvesters. The previous research approaches for enhancing the triboelectric charges can be classified into three categories: i) materials type, ii) device structure, and iii) surface modification. In this review article, we focus on various mechanisms and methods through the surface modification beyond the limitations of structural parameters and materials, such as surficial texturing/patterning, functionalization, dielectric engineering, surface charge doping and 2D material processing. This perspective study is a cornerstone for establishing next-generation energy applications consisting of triboelectric energy harvesters from portable devices to power industries.
