Energy harvesting through a piezoelectric sensor

Energy harvesting through motion caused by wind is a unique way of finding an alternative energy source for several electronic devices. Piezo-electronic sensors, which harvest energy from small vibrations and movements, are investigated by many researchers nowadays. This paper conducted an experimental study to find an alternative energy source for diverse electronics with forced oscillations from a fan. The relations between the force applied by wind and the oscillation of a paper strip were studied.

Flexible, Sensitive, Multifunctional Rubber-based Sensor with Multiple Responses to Infrared, Temperature, Humidity and Strain

Flexible wearable electronic sensors have attracted immense interest in human motion detection, body temperature monitoring and personal healthcare monitoring. However, most of reported sensors cannot integrate multifunctional applications at the same time though they own excellent single achievement of strain sensing or humidity sensing. Herein, we fabricate a multifunctional rubber-based flexible sensor (MRFS) with responses to infrared, temperature, humidity and strain. The sensor owns a superior strength (5.66 MPa), high stretchability (367%), high temperature coefficient of resistance (2.046%/℃) and high photothermal conversion efficiency (78.6%). For the sensing applications, it shows a rapid sensing of only 0.5 s for the temperature and humidity changes as well as a sensitive response to low-powered near infrared of 0.14 W/cm2, body temperature change from 33.6 to 35.6 ℃, and small amount of moisture on human skin. Moreover, the MRFS shows a considerable strain sensing for human joint motion and an antibacterial property.

Impact of Technology on Agriculture Workers in Tirunelveli District

The main purpose of this paper is to introduce the technology impact of agriculture workers in Tirunelveli District. In the last century, the basic agriculture technology like machines has changed a little. Though the modern technology, planters and harvesters do a better job or are slightly tweaked from their predecessors. However, the modern technology is changing the way that humans operate the machines, GPS locators, as computer monitoring systems and self-steer programs allow the most advanced tractors and implements to be more precise and less wasteful in the use of fuel, fertilizer or seed. In future, there may be mass production of driverless tractors and other agriculture machinery which use electronic sensors and GPS maps.

Evaluación de la Viabilidad Técnica para la Captación del Agua Atmosférica acorde a las Condiciones Climatológicas del Municipio de Facatativá / Evaluation of the Technical Viability for the Atmospheric Water Capture according to the Climatological Conditions of Facatativá, Colombia

The aim of this work was to determine the technical feasibility to obtain atmospheric water according to the weather conditions in Facatativá, Colombia. Atmospheric water capture is an alternative source for a population with limited access to water resources. This problem is especially serious for vulnerable communities that require the development of new sources of water supply. For the development of this work, three phases were considered: Climatological dataset related with relative humidity and temperature in Facatativá were obtained from the IDEAM Villa Inés Station for the period 2006 - 2016. With these data the maximum amount of condensable water per kilogram of air and operating ranges for the experimental setup were calculated. The second phase involved of an experimental setup consisting of a glass chamber connected to two Peltier cells. Saturated air was fed into the chamber. A 24 factorial design was carried out where the factors were the air inlet flow and the temperature. The humidity and temperature data of the outlet air were obtained by means of electronic sensors. Finally, the interpretation of data and results of the water obtained were used to calculate the efficiencies of the process. The results of this work demonstrate the technical feasibility of obtaining water from humid air and propose improvements for the establishment of future assemblies.

Animal Borne Ocean Sensors – AniBOS – An Essential Component of the Global Ocean Observing System

Marine animals equipped with biological and physical electronic sensors have produced long-term data streams on key marine environmental variables, hydrography, animal behavior and ecology. These data are an essential component of the Global Ocean Observing System (GOOS). The Animal Borne Ocean Sensors (AniBOS) network aims to coordinate the long-term collection and delivery of marine data streams, providing a complementary capability to other GOOS networks that monitor Essential Ocean Variables (EOVs), essential climate variables (ECVs) and essential biodiversity variables (EBVs). AniBOS augments observations of temperature and salinity within the upper ocean, in areas that are under-sampled, providing information that is urgently needed for an improved understanding of climate and ocean variability and for forecasting. Additionally, measurements of chlorophyll fluorescence and dissolved oxygen concentrations are emerging. The observations AniBOS provides are used widely across the research, modeling and operational oceanographic communities. High latitude, shallow coastal shelves and tropical seas have historically been sampled poorly with traditional observing platforms for many reasons including sea ice presence, limited satellite coverage and logistical costs. Animal-borne sensors are helping to fill that gap by collecting and transmitting in near real time an average of 500 temperature-salinity-depth profiles per animal annually and, when instruments are recovered (∼30% of instruments deployed annually, n = 103 ± 34), up to 1,000 profiles per month in these regions. Increased observations from under-sampled regions greatly improve the accuracy and confidence in estimates of ocean state and improve studies of climate variability by delivering data that refine climate prediction estimates at regional and global scales. The GOOS Observations Coordination Group (OCG) reviews, advises on and coordinates activities across the global ocean observing networks to strengthen the effective implementation of the system. AniBOS was formally recognized in 2020 as a GOOS network. This improves our ability to observe the ocean’s structure and animals that live in them more comprehensively, concomitantly improving our understanding of global ocean and climate processes for societal benefit consistent with the UN Sustainability Goals 13 and 14: Climate and Life below Water. Working within the GOOS OCG framework ensures that AniBOS is an essential component of an integrated Global Ocean Observing System.

Frontiers Approaches to the Diagnosis of Thrips (Thysanoptera): How Effective Are the Molecular and Electronic Detection Platforms?

Thrips are insect pests of economically important agricultural, horticultural, and forest crops. They cause damage by sucking plant sap and by transmitting several tospoviruses, ilarviruses, carmoviruses, sobemoviruses, and machlomoviruses. Accurate and timely identification is the key to successful management of thrips species. However, their small size, cryptic nature, presence of color and reproductive morphs, and intraspecies genetic variability make the identification of thrips species challenging. The use of molecular and electronic detection platforms has made thrips identification rapid, precise, sensitive, high throughput, and independent of developmental stages. Multi-locus phylogeny based on mitochondrial, nuclear, and other markers has resolved ambiguities in morphologically indistinguishable thrips species. Microsatellite, RFLP, RAPD, AFLP, and CAPS markers have helped to explain population structure, gene flow, and intraspecies heterogeneity. Recent techniques such as LAMP and RPA have been employed for sensitive and on-site identification of thrips. Artificial neural networks and high throughput diagnostics facilitate automated identification. This review also discusses the potential of pyrosequencing, microarrays, high throughput sequencing, and electronic sensors in delimiting thrips species.
