A hybrid energy utilization technology using solar for desalination and extracting electricity from an evaporation induced salinity gradient is presented.
Advances in mobile networks and low-power electronics have driven smart medical devices at a tremendous pace, evoking increased interest household healthcare, especially for those with cardiovascular or respiratory disease. Thus, flexible battery-free pressure sensors, great potential monitoring respiration heartbeat way, are urgently demanded. However, traditional sensors subtle physiological signal detecting mostly tightly adhered onto the skin instead of working under body weight...
Abstract Implantable ultrasonic energy harvesters that scavenge wireless mechanic from ultrasound own remarkable potential in advanced medical protocols for neuroprosthetics, power, biosensor, etc. The main challenge this kind of device is to achieve high‐efficiency conversion a weak pressure field. Here, multilayered piezoelectret with strain enhanced piezoelectricity by introducing parallel‐connected air hole array an interdielectric layer sandwiched between pair electrets efficient...
Recently, wearable and breathable healthcare devices for air filtering real-time vital signs monitoring have become urgently needed since virus particulate matter (PM) cause serious health issues. Herein, we present a trap-induced dense monocharged hybrid perfluorinated electret nanofibrous membrane (HPFM) highly efficient ultrafine PM0.3 removal with an efficiency of 99.712% under low pressure drop (38.1 Pa) high quality factor 0.154 Pa-1. Furthermore, recyclable multifunctional mask is...
The traditional Chinese medicine Qing'e Pills (QEP) has been used to treat postmenopausal osteoporosis (PMO).We evaluated the regulatory effects of QEP on gut microbiota in osteoporosis.Eighteen female SD rats were divided into three groups: sham surgery (SHAM), ovariectomized (OVX) and treated with (OVX + QEP). Six weeks after ovariectomy, was administered OVX for eight (4.5 g/kg/day, i.g.). After 14 weeks, bone microstructure evaluated. Differences analysed via 16S rRNA gene sequencing....
Soft, low-cost, high-performance generators are highly desirable for harvesting ambient low frequency mechanical energy. Here, a dielectric elastomer nanogenerator (DENG) is reported, which consists of capacitor, an electret electrostatic voltage source, and charge pump circuit. Under biaxial stretching, DENG can convert tensile energy into electrical power without any external supply. Different from traditional DEG with the outward transfer in direct current (DC), works based on shuttle...
Dielectric elastomer generator (DEG) is a solid-state electrostatic device with variable capacitance. As an energy harvester, it should be passive, high performance, and fatigue-resistant. However, no such DEGs can satisfy these requirements simultaneously as the performance strongly depends on external voltage large capacitance change, which are prone to dielectric film fatigue failure. In this study, we developed passive alternating current (AC-DEG) reconcile contradiction requirements....

Different FIV phenomena Re increasing are reported. In vortex-induced (VIV) branch, amplitude energy harvest efficiency higher than those rotation, situation is opposite in VIV-galloping transition galloping branches. Checking wake vortex indicated that change angle attack caused by was cause...
By virtue of simple fabrication, low cost, and high conversion efficiency, nanogenerators play a key role in promoting the development self-powered systems large-scale mechanical energy harvesting. Efforts have been ongoing for improving output power by maximizing their surface charge density via modification or structure optimization. Nevertheless, because inevitable air breakdown during operation process, enhancing is not retainable, which most crucial limitation performance...
Polytetrafluoroethylene (PTFE) is a fascinating electret material widely used for energy harvesting and sensing, an enhancement in the performance could be expected by reducing its size into nanoscale because of higher surface charge density attained.
