우리가�흔히�마주하는�작은�물방울속에는�많은�역학적�원리가�숨어있습니다.

산업�혁명�이후, 세계�경제의�고도성장을�이끌어�온�자동자, 조선, 중공업, 등�산업�분야는 body force (중력�등�질량에�비례하는�힘)에�의해�지배되는�거시�규모의�세상(macro world)이었습니다.

이에�반해, 미래를�이끌어가고�있는�바이오, 의료, 반도체, 등�나노�기술�기반의�첨단�분야는�표면�역학 (계면�에너지, 표면�장력, 젖음성�등)에�의해�지배되는 미시�규모의�세상(micro world)입니다.

현재, 전반적인�공학�영역은 Macro world의 body force에�대한�해석과�이해에�초점이�맞추어져�있고미래�기술의�핵심이�되는 Micro world의�표면�역학에�대한�이해는�극히�미비합니다.

피�한�방울로�질병을�진단하고

작은�칩�하나로�고통�없이�질병을�치료하는

우리가�꿈꾸는�미래의�기술들 (바이오�칩, 미세�유체, Lab on a chip 등)

“Micro world”가�이끄는�미래를 SmartDrop이�함께�준비합니다.

기존의�장비는�일반적으로�접촉선�부근의�임의의�점 3~4개를�이용하여�근사한�값으로�접촉각을�측정합니다.

이�경우, 중력으로�인한�왜곡�또는�광학적�왜곡을�걸러내지�못하고�왜곡된�면의�점을�잡아서�측정하기�때문에

결과에�오차가�생기게�됩니다.

특히, 고점도�용액이나�초소수성�표면의�경우�더�큰�오차가�발생합니다. (타사�장비 10 이상)

SmartDrop은�독자�기술이�적용된�수치�해석�기반의 GEM engine을�탑재하여 왜곡이�없는�면인 free surface를�이용하여 300~600개의�점으로�계산하기�때문에�현존하는�장비�중�가장

높은�정확도를�자랑합니다. (현재 SmartDrop의�오차범위 0.1 이내 )

SmartDrop 시작부터�다릅니다.

연구�장비는�어렵다?SmartDrop은�최고의�편의성을�자랑합니다.

또한, SmartDrop은�실험�과정의�모든�데이터를�실험별, 날짜별, 시간별로�저장(CSV파일)하여,

사용자가�원하는�그래프로�쉽게�나타낼�수�있습니다.
