I whakamahia e Leonardo Da Vinci ngā tūranga o ngā taumaha taurite kua whakatikatikaina ki runga i tētahi rīpene mīhini hei whakataurite me te whakatau i ngā taumaha kāore i te mōhiotia. Ko te rerekētanga o āna hoahoa i whakamahi i ngā rīpene maha, he rerekē te roa o ia rīpene, ā, he kotahi te taumaha paerewa i tauritehia. I mua i te whakakapinga o ngā rīpene mīhini e ngā pūtau kawenga ine taumaha waipēhi me te hiko mō ngā tono pauna ahumahi, i whānuitia te whakamahinga o ēnei pauna rīpene mīhini. I whakamahia ēnei hei pauna i ngā mea katoa mai i ngā pire ki ngā waka tereina, ā, i mahia i te mea tika me te pono mena ka whakatikatikaina me te pupuri tika. I uru atu ki te whakamahinga o tētahi tikanga whakataurite taumaha, te kimi rānei i te kaha i whakawhanakehia e ngā rīpene mīhini. Ko ngā pūoko kaha i mua i te ine taumahatanga i whakaurua ki ngā hoahoa waipēhi me te hau.

I te tau 1843, i hangaia e te tohunga ahupūngao Piritana, a Charles Wheatstone, tētahi ara iahiko piriti hei ine i ngā ātete hiko. He pai te ara iahiko piriti Wheatstone mō te ine i ngā huringa ātete e puta ana i roto i ngā ine taumahatanga. Ahakoa i whakawhanakehia te ine taumahatanga waea ātete hono tuatahi i ngā tau 1940, tae noa ki te wā i eke ai ngā hikohiko hou ki te taumata hangarau me te ōhanga ka taea te whakamahi i te hangarau hou. Heoi, mai i taua wā, kua horapa haere ngā ine taumahatanga hei wāhanga tauine miihini me ngā pūtau kawenga takitahi. I ēnei rā, haunga ētahi taiwhanga e whakamahia tonutia ana ngā pauna miihini tika, ko ngā pūtau kawenga ine taumahatanga te nuinga o te umanga pauna. I ētahi wā ka whakamahia ngā pūtau kawenga hau i ngā wāhi e hiahiatia ana te haumaru me te akuaku o roto, ā, ka whakaarohia ngā pūtau kawenga waipēhi i ngā wāhi tawhiti, nā te mea kāore e hiahiatia he pūtake hiko. Ka tukuna e ngā pūtau kawenga ine taumahatanga te tika mai i roto i te 0.03% ki te 0.25% tauine katoa, ā, he pai mō te nuinga o ngā tono ahumahi.
