Looking toward world technology trends over the next few decades, self-powered sensing networks are a key field of technological and economic driver for global industries. Since 2006, ZhongLinWang’s group has proposed a novel concept of nanogenerators (NGs), including piezoelectric nanogenerator and triboelectric nanogenerator, which could convert a mechanical trigger into an electric output. C...
Rotational energy has been a key element in many domestic and industrial areas from wristwatches to offshore wind turbines. It utilized on large scale megawatt-scale hydraulic power generators kilowatt-scale vehicles rotating machines, watt-scale hand-held tools, milliwatt (microwatt) rotational harvesters. The scope of this review is microwatt-level harvesters (millimeter centimeter size) that...
The self-powered sensing system could harness ambient energy to power the sensor without need for external electrical energy. Recently, concept of photovoltaic (PV) gas has aroused wider attentions due room-temperature operation, low consumption, small size and potential applications. PV sensors integrate effects function into a single chip, which truly achieve goal zero consumption an independ...
This study examined the electrical and self-sensing capacities of ultra-high-performance fiber-reinforced concrete (UHPFRC) with and without carbon nanotubes (CNTs). For this, the effects of steel fiber content, orientation, and pore water content on the electrical and piezoresistive properties of UHPFRC without CNTs were first evaluated. Then, the effect of CNT content on the self-sensing capa...
the purpose of this study was to find the relationship between critical thinking and self-regulation with reading comprehension of iranian female elementary language learners. the present study is a correlational one having a descriptive design. two questionnaires, critical thinking questionnaire and self-regulation questionnaire which were valid and reliable questionnaires and four reading com...
this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
Structural health management (SHM) of safety-critical structures requires multiple capabilities: sensing, assessment, diagnostics, prognostics, repair, etc. This paper presents a capability for self-organising diagnosis by a group of autonomous sensing agents in a distributed sensing and processing SHM network. The diagnostics involves acoustic emission waves emitted as a result of a sudden rel...
The paper studied the noise elimination methods for the signals observed from a self-mixing-laser diode (SMLD) based sensing system. The core part of the sensing system consists of a LD, a lens and an external vibrating target. The proposed noise elimination methods are applied on both the simulated and experimental sensing signals. The results presented in the paper show the noise contained in...
