Theinternationalteam,ledbytheUniversityof Cambridge,havepreviouslydemonstrated thatwovendisplayscanbemadeatlarge sizes,buttheseearlierexamplesweremade usingspecializedmanuallaboratory equipment.Othersmarttextilescanbe manufacturedinspecializedmicroelectronic fabricationfacilities,butthesearehighly expensiveandproducelargevolumesof waste.

However,theteamfoundthatflexibledisplays andsmartfabricscanbemademuchmore cheaply,andmoresustainably,byweaving electronic,optoelectronic,sensingandenergy fibercomponentsonthesameindustrial loomsusedtomakeconventionaltextiles. Theirresults,reportedinthejournalScience Advances,demonstratehowsmarttextiles couldbeanalternativetolargerelectronicsin

Despiterecentprogressinthedevelopmentof smarttextiles,theirfunctionality,dimensions andshapeshavebeenlimitedbycurrent manufacturingprocesses.

“Wecouldmakethesetextilesinspecialized microelectronicsfacilities,buttheserequire billionsofpoundsofinvestment,”saidDr SanghyoLeefromCambridge’sDepartment ofEngineering,thepaper’sfirstauthor.“In addition,manufacturingsmarttextilesinthis wayishighlylimited,sinceeverythinghasto bemadeonthesamerigidwafersusedto makeintegratedcircuits,sothemaximumsize wecangetisabout30centimetersin diameter.”

“Smarttextileshavealsobeenlimitedbytheir lackofpracticality,”saidDrLuigiOcchipinti, alsofromtheDepartmentofEngineering,who co-ledtheresearch.“Youthinkofthesortof bending,stretchingandfoldingthatnormal fabricshavetowithstand,andit’sbeena challengetoincorporatethatsamedurability intosmarttextiles.”

Lastyear,someofthesameresearchers showedthatifthefibersusedinsmarttextiles werecoatedwithmaterialsthatcanwithstand stretching,theycouldbecompatiblewith conventionalweavingprocesses.Usingthis technique,theyproduceda46-inchwoven demonstratordisplay.

Now,theresearchershaveshownthatsmart textilescanbemadeusingautomated processes,withnolimitsontheirsizeor shape.Multipletypesoffiberdevices, includingenergystoragedevices, light-emittingdiodes,andtransistorswere fabricated,encapsulated,andmixedwith conventionalfibers,eithersyntheticornatural, tobuildsmarttextilesbyautomatedweaving. Thefiberdeviceswereinterconnectedbyan automatedlaserweldingmethodwith electricallyconductiveadhesive.

Theprocesseswerealloptimizedtominimize damagetotheelectroniccomponents,which inturnmadethesmarttextilesdurableenough towithstandthestretchingofanindustrial weavingmachine.Theencapsulationmethod wasdevelopedtoconsiderthefunctionalityof thefiberdevices,andthemechanicalforce andthermalenergywereinvestigated systematicallytoachieveautomatedweaving andlaser-basedinterconnection,respectively.

LightingControlSystemsfor Agriculture

LEDlightingisgainingpopularityinthe fieldofagriculture,especiallyinanimal husbandry,greenhouses,andindoor farming,whereitprovidesseveralbenefitsovertraditionallightingmethods suchasbeingmaintenance-freeand havingahigherenergyefficiency— LEDsconvertmorethan80%ofthe electricitytheyconsumeintolight andconsume60%lessenergyforthe samelightingintensity.However,the biggestadvantageisspectrumcontrol: differentcropsandanimalsrequiredifferentwavelengthsoflightforoptimal growth,yield,andwell-being,andLED lightingcanprovidetheexactspectrumneededwiththeaddedbenefit thatthisspectrumcanbeoptimizedin real-time.Thisabilitytofine-tunethe colortemperaturemakesLEDlighting acost-effectivesolution,eventhough itsinitialcostmaybehigherthanthat oftraditionallightingmethods.

TheImportanceofLED LightinginAnimal Husbandry

LEDlightingisusedinanimalhusbandry toimproveanimalwelfare,growth,and productivity.Properandadequatelightingiscrucialforanimalwell-beingand growth,andLEDlightingcanprovidethe exactspectrumoflightneededfordifferent stagesofanimaldevelopment.

Aspreviouslymentioned,LEDlighting offersprecisespectrumcontrol,which meansthatthelightcanbetailoredtothe specificneedsofplants;theclassicgrow lampsradiatemorestronglyinthecolors,magentaandblue.However,different wavelengthsoflightarerequiredfordifferentstagesofplantgrowth,andLED lightingcanprovidetheoptimalspectrum foreachstage.Anotheradvantageisthat itproduceslessheatandinfraredradiationthantraditionallightingmethods,thus reducingtheriskofheatstressonplants underhighilluminationlevels.Thisisespeciallyimportantinindoorfarmingand greenhousecultivation,wheretemperature controliscritical.

LEDlightingprovidesthenecessarylight forplantgrowthineachlayer,reducing energyconsumptionandheatoutput.In hydroponicfarming,plantsaregrownin anutrient-richwatersolutionwithoutsoil, andLEDlightingcanoffertherightspectrumoflightforphotosynthesis,allowing plantstogrowfasterandproducehigher yields;itcanalsobecustomizedtomatch thespecificlightrequirementsofdifferentplantspecies.Avariationonsoil-less horticultureisaeroponicfarming,where plantsaregrowninanairormistenvironment,andaquaponicfarming,whereplants aregrowninawater-basedenvironment withfish.Again,LEDlightingisusedto providethenecessaryspectrumoflight foroptimumplantgrowthandtosupport thegrowthofaquaticorganisms.Indoor farmingisbecomingincreasinglypopular, especiallyinurbanareaswherespaceis limited.Here,LEDlightingplaysacritical role,asitprovidesthenecessarylightfor plantgrowthwhilereducingenergyconsumptionandheatoutput.

MusaUNMEHOPA,HeadofWirelessStandards&Regulationsat Signify

SmartLightinghasarguablybeenone ofthemoresuccessfulSmartHome usecasesoverthepastyears.Lightingcompanies,fromallregionsaround theglobe,offerwirelesslightingcontrolproducts,andconnectedlamps andluminaires,aspartoftheirportfolios.Butithasnotbeenwithoutchallenges.Andothersmarthomeuse casesbeyondsmartlighting,suchas smarthomeenergymanagement(thermostats,airconditioning,heatingand ventilation),smarthomesafety(windowanddoorsensors,proximityand motionsensors,cameras),smarthome accesscontrol(doorlocks,gates, shadesandblinds)arefacingmany ofthesamechallenges.Asaresult, theSmartHomeisnotubiquitousyet. Onecomplicatingfactoristhatthese challengesarepresentacrosstheentirevaluechain,fromconsumers,to devicemanufacturers,tosmarthome ecosystems,allthewaytoretailers. Let’stakealookatsomeofthechallengesfacedbythesefourstakeholder groups,andthenpresentasolution thatcouldbenefitallofthem,aswe progressalongtheSmartHomejourneyfromcoolgadgettoubiquitous infrastructure.

TheChallenges

Consumerchallenge –Asaconsumer,I needtoworkoutifthesmartdevicethat Ipickedoutinthestore,willactuallywork withthesmartdevicesandthesmarthome ecosystemIalreadyhaveinmyhome.And thisisnotjustontheprotocollevel(e.g. doIhaveZigbeeinmyhomeorsomething else),butalsoontheecosystemorsmart hublevel(e.g.doIhaveAmazonEcho, AppleHomeKit,GoogleHome,Samsung SmartThings,etc.).AnotherissueIface asaconsumeristhatofsupport.IfIbuy adevicefromacompanythatlaterondiscontinuestheirsupport,orthecompany goesunder,mycontrolappforthatdevice stopsworkingandIamleftwithabricked device.

Re-FitLightingSolution: Backgrounds–LightingConcept–BusinessSuccess

PeterHAUMER,HeadofTechnicalSalesatLumitech/Kiteo

Currentchallengesduetothebanon fluorescenttubes,explodingenergy costs,andthedemandforsustainabilityrequireintegrativethinking.Solving thisisanopportunityforboththelightingindustryandtheuser.

Butthereareseveraldrawbacksbecause thisprocedurehasquitealotofstumbling blocks:

• Onefinancialissueisthattypicallythe mereexchangeofthelightsourceis outsidethescopeofenvironmentalsubsidies.

• Itisjustasimportanttoknowthatfollowingthenormativeregulationsand applicablestandards,thelightsource exchangemeansaninterventionin theluminaireandanevidenttechnical changetotheoriginalarrangement.
