A Superhydrophobic Droplet‐Based Magnetoelectric Hybrid System to Generate Electricity and Collect Water Simultaneously

Abstract

are heavy, bulky, and immovable and are generally situated near dams, coasts, or river banks. [3-5] Furthermore, generating electricity using a traditional electromagnetic apparatus is difficult under low water supply, such as rainwater or fog. [6] Therefore, a small, novel, and portable electromagnetic system that can harvest energy from tiny water drops can act as a water-electricity transducer; such a system is an alternative to traditional hydropower equipment. Bioinspired superhydrophobic materials have low surface energy and microor nano-scale surface roughness, [7-9] rendering their unique capability to manipulate water droplets. By carefully designing and controlling the superhydrophobic surfaces, water drops can pin, [10] roll, [11] separate, [12] jump, [13] and react [14] and, therefore, can possess a variety of

Current Detection and Energy Harvesting Integrated Magnetoelectric Sensor with Flexibility and Heat Resistance Based on Polylactide/VB2 Composites and FeCoV

“…In addition, the MCS can covert the magnetic field into electricity to achieve energy harvesting. [40][41][42] Figure 7a shows the digital photo of MCS when measuring the current of a mobile phone. In Figure 7b, when the mobile phone change from standby state to calling states, its working current will certainly change, and the corresponding waveform/value of output voltage of MCS will synchronously change, which may provide information to judge the working state of mobile phone.…”

3D‐Printed Underwater Super‐Oleophobic Shark Skin toward the Electricity Generation through Low‐Adhesion Sliding of Magnetic Nanofluid Droplets

“…[ 1–6 ] Converting mechanical energy to electricity provides no doubt one of promising sustainable energies. [ 7–11 ] Among diverse conversion approaches, the magnetoelectric strategy has been proved to be effective and stably used in our daily lives for more than 150 years. However, such a strategy is often susceptible to rigid and heavy setups, difficulty to carry and limited applied locations such as power plants.…”

Magnetic‐Sensitive Crack Sensor with Ultrahigh Sensitivity at Room Temperature by Depositing Graphene Nanosheets upon a Flexible Magnetic Film

“…[ 1–6 ] Owing to unique touchless sensing, and magneto‐sensitive properties, magnetic field sensor exhibits a promising application at health monitoring, human–machine interfaces, and medical diagnosis. [ 7–16 ] Currently, flexible magnetic field sensors mainly include fluxgate magnetic sensors, [ 17,18 ] Hall sensors, [ 19–21 ] and magnetoresistance sensors. [ 22,23 ] Schoinas et al., reported a flexible fluxgate magnetic sensor with sensitivity of 14 620 V T −1 at 200 KHz.…”
