Electricity-generating devices are among the most popular recent topics due to increasing global energy requirements, which have propelled many researchers to investigate different approaches. One approach involves electroreceptive animals. In this regard, we proposed a polymer-based energy generator converting Gibbs free energy into usable electricity. We developed a polymer-based device inspired by electric eels and modified it to extend the maximum power generation limits by adding nickel-nickel and aluminumcopper current collector (CC) backings. Thus, the imitation of electrocytes and the aims to increase the voltage, which was generated by taking advantage of electrochemical reactions between metals and polymers, were successfully achieved. In each tetrameric package ($ 0:8 cm 3 ) supported by nickel-nickel CCs, the voltage output was more than 350 mV, while tetrameric cells with copper-aluminum CC pairs led to an open-circuit voltage of more than 900 mV. The conversion of free energy into electricity is attributed to the electricity generation of cells supported by the Ni-Ni CC pair to the ion gradient between the layers, as in electrocyte. In the case of using Cu-Al CCs, electrochemical reactions between the supporting metals and polymers are prominent. The generation of such high voltages is due to the ion concentration gradient and electrochemical interactions. Only slight changes in the output voltage value related to the corrosion on the aluminum CC in time provide a distinctive advantage for long-term power needs. Thus, it can be stated that this bioinspired energy-generating device offers the potential for eventually becoming a power source for small-scale electrical systems and for fulfilling daily personal energy needs.

“…Another benefit of PDMS is that microchips with single or double layers can be obtained. 46,68 Nevertheless, the presence of CH 3 groups on the entire surface of PDMS makes it hydrophobic, which is regarded as a drawback for its application in microfluidics. Accordingly, higher pressure is required to keep the fluid flow in the case of using PDMS.…”

“…An easy way to achieve a microfluidic chip with a PDMS substrate is the utilization of a device mold; in this technique, curing agents together with the elastomer are mixed, and then they are cast and subjected to heat.

Biosensors are valuable tools for the detection of biological species, including cells, pathogens, proteins, and other biological molecules. Biosensing devices integrated with microfluidics not only allow for easier sample preparation, portability, and reduced detection time and cost but also offer unique features such as label-free detection and improved sensitivity. Cardiovascular diseases (CVDs), particularly acute myocardial infarction, which is considered one of the main causes of death, are currently diagnosed by electrocardiography (ECG), which has been proven to be inadequate. To overcome the limitations of ECG, the efficient detection of cardiac biomarkers and specifically the measurement of cardiac troponins (cTnT and cTnI) are suggested. This review aims to expound on microfluidics, the most recent materials to develop these devices, and their application in medical diagnosis, particularly in CVD detection. Moreover, we will explore some of the prevalent and last readout methods to investigate in-depth electrochemical label-free detection methods for CVDs, primarily based on voltammetry and electrochemical impedance spectroscopy, with the main focus on structural details.

“…For even more pronounced control over wettability, very recently, topography modifications were combined efficiently with chemical treatment of various surfaces including cotton [33,34], steel [35] and synthetic leather [36]. Further examples include trichloro(1H,1H,2H,2H-perfluorooctyl) silane (PFOCTS)-modified cobalt structures for creating omniphobic surfaces [37], Cd-Si co-doped TiO2 thin films examining the synergistic effect of co-dopants and calcination temperature on wettability [38], as well as polymer nanocomposite surfaces comprising Au/ZnO nanoparticles randomly dispersed in a cellulose acetate polymer matrix [39]. A detailed compilation of substrate coatings and associated fabrication techniques can be found in the comprehensive work of B. Bhushan and S. Martin [40].…”

Predicting wettability accurately across various materials, surface topographies and wetting liquids is undeniably of paramount importance as it sets the foundations for technological developments related to improved life quality, energy saving and economization of resources, thereby reducing the environmental impact for recycling and reuse. In this work, we extend and validate our recently published wetting model, constituting a refinement of the original Cassie-Baxter model after consideration of realistic curved liquid-air interfaces. Our model enabled more meaningful contact angle predictions, while it captured the experimentally observed trends between contact angle and surface roughness. Here, the formalism of our
