Project aim: Development of critical components for wearable electronics for aplication in precision agriculture.
&nbsp;
About the project: Current demands in wearable electronics for application in precision agriculture are small dimensions, low cost, and flexibility of devices. The most critical part in the design of wearable electronics devices is a power interface. Research in this project is divided into three tasks. The first task is focused on development of planar, flexible magnetic components. The second task is focused on development of components for energy harvesting. The third task is focused on development of components for energy storage. A high degree of flexibility and miniaturization will be required for fabrication methods. Possible application of the results is in small, wearable and wireless systems, which are used in precision agriculture as well as in health applications, monitoring, industry, etc.

Energy Harvesting

&nbsp;

Next generation technologies, such as the IoT and 5G technology, create a digitally connected world, which improves the standard of life of people, particularly health, productivity, and communication. Small electronic devices such as sensors, actuators, and wireless transmitters have been integrated into day to day objects around us, including the human body, buildings, biochemical detection, environmental protection, security etc. Powering these electronics with the required complexity and mobility remains one of the key challenges.

Nanogenerators emerge as the leading candidates as a potential energy source for powering autonomous IoT applications. Our particular focus are triboelectric and hybrid nanogenerators. Triboelectric technology depends on the conjunction of triboelectrification and electrostatic induction through the relative sliding or contact/separation between two materials that possess opposite tribopolarity. Hybrid nanotechnology harvest the same kind of energy by simultaneously using multiple types of generators based on different working mechanisms. A hybridized mechanical (biomechanical)-energy-harvesting technology enhance the overall power output.

&nbsp;

&nbsp;

Energy Storage

&nbsp;

Recent advances in development of miniaturized electronic devices has increased the demand for energy systems with optimized capacity, cycle life, power, and environmental impact. Energy storage devices have been identified as important electronic components for environmental and sustainable protection and efficient energy development and storage. Sustainable energy research has led to development of novel energy storage systems, particularly for the utilization of renewable energy. A promising solution to address this challenge is the development of efficient electrochemical energy storage systems like batteries and supercapacitors.

&nbsp;

Supercapacitors as high-performance energy storage devices are particularly important for building a micropower system, which would power up portable and wearable devices for a long time without maintenance. Their main advantages are portability, low environmental impact, flexibility, stability, safety, light-weight, high power density, and long cycle life. Our focus is on developing ultra-thin solid-state and flexible microsupercapacitors.

Cilj projekta: Razvoj prototipova kritičnih komponenti za projektovanje prenosivih elektronskih sistema koji se koriste u preciznoj poljoprivredi.
&nbsp;
O projektu: Zahtevi koji se postavljaju pred savremene prenosive elektronske uređaje u preciznoj poljoprivredi su male dimenzije, niska cena i fleksibilnost. Najkritičniji deo predstavlja projektovanje interfejsa koji reguliše napajanje uređaja. Istraživanje u okviru ovog projekta je podeljeno u tri faze. Prva faza istraživanja je usmerena na razvoj planarnih, fleksibilnih magnetnih komponenti. Druga faza itraživanja je usmerena na razvoj komponenti za konverziju neiskorišćene energija iz prirode u korisne oblike. Treća faza itraživanja je usmerena na projektovanje komponenti za skladištenje energije. Akcenat fabrikacije će biti na visokom stepenu fleksibilnosti i minijaturizacije. Mogućnost primene rezultata je u malim, prenosivim i bežičnim sistemima koji se koriste u preciznoj poljoprivredi, ali i šire u zdravstvu, monitoringu, industriji, itd.

Sistemi za prikupljanje energije

&nbsp;

Nove generacije tehnologija, kao što su Internet of Things (IoT) i 5G tehnologija, unapređuju životni standard, stvarajući digitalno povezani svet, u kome će zdravlje, produktivnost i komunikacija biti znatno poboljšani. To podrazumeva prisustvo integrisanih minijaturnih elektronskih uređaja u objektima koje svakodnevno koristimo, uključujući ljudsko telo, zgrade, biohemijsku detekciju, zaštitu životne sredine, itd. Takvi sistemi su sve više izvodljivi zahvaljujući razvoju elektronike male snage i IoT aplikacijama. Međutim, napajanje ove elektronike koja zahteva kompleksnost i mobilnost, ostaje jedan od ključnih izazova. Prikupljanje energije iz ambijentalnih izvora energije pokazalo se kao pouzdan pristup u ispunjavanju zahteva u vezi sa energijom i performansama. Vodeći kandidati za napajanje autonomnih IoT aplikacija su nanogeneratori.

&nbsp;

Fokus našeg istraživanja su triboelektrični i hibridni nanogeneratori. Triboelektrični nanogenerator se pokazao kao efektan i robustan način prikupljanja ambijentalne mehaničke energije koji povezuje triboelektrični efekat i elektrostatičku indukciju. Hibridni nanogeneratori omogućavaju simultano prikupljanje istog tipa energije korišćenjem više različitih principa konverzije energije i značajno veću efikasnost konverzije mehaničke/biomehaničke energije u električnu energiju.

&nbsp;

&nbsp;

&nbsp;

Sistemi za skladištenje energije

&nbsp;

Razvoj minijaturizovanih elektronskih uređaja povećao je zahtev za sistemima energije sa optimizovanim kapacitetom, životnim vekom, snagom i uticajem na životnu sredinu. Sistemi za skladištenje energije su identifikovani kao važne elektronske komponente za održivu zaštitu životne sredine i efikasno skladištenje energije. Vodeći kandidati za skladištenje energije su elektrohemijski sistemi kao što su baterije i superkondenzatori.

&nbsp;

Superkondenzatori kao uređaji visokih performansi za skladištenje energije posebno su važni za dugoročno napajanje prenosivih uređaja i uređaja integrisanih u odeću. Osnovne prednosti superkondenzatora su prenosivost, nizak uticaj na životnu sredinu, fleksibilnost, stabilnost, sigurnost, mala težina, velika gustina snage i dugačak životni vek. Fokus našeg istraživanja su ultra tanki mikrosuperkondenzatori fabrikovani na čvrstim i fleksibilnim supstratima.
