Kua tutuki i ngā kairangahau tētahi taumata whakangao nui me ngā tohu RFID tānga hurihuri-ki-hurihuri e utu ana i raro i te $0.002 ia waeine – he whakahekenga 90% mai i ngā tohu tuku iho. Ko te kaupapa auaha e aro ana ki ngā pūihi graphene kua whakakikoruatia ki te laser e tutuki ana i te 8 dBi te whakanui ahakoa he 0.08mm te matotoru, e hototahi ana ki ngā awa hangarua pepa paerewa.

Mā tēnei putanga hou ka taea te tāpiri i te tohu nui o ngā taonga pau iti te utu i whakaarohia i mua he mea kore e taea te whakamahi. He pai te whakaatu a ngā whakamātautau rongoā: Mā te whakaurunga o te kete mirumiru ka taea e ngā tūroro te whakaū i te pono o te rongoā me te aroturuki i te tutuki i te horopeta mā roto i ngā taputapu NFC.

I whakawhanakehia e tētahi tīma pūtaiao rauemi i tētahi whare wānanga rangahau o Amerika ngā tikanga whakatakoto matū whakarei ake i te plasma (PECVD) hei hono tika i ngā paparanga graphene ki ngā papa pirau. "E 98% te whakamahinga rauemi e whakamahia ana e tā mātou tukanga, ki te whakaritea ki te 60% i roto i ngā tikanga whakairo tuku iho," te kī a te kaiārahi kaupapa, nāna nei i whiwhi $15 miriona i roto i te pūtea ā-motu mō ngā whare whakaputa whakamātautau.

Kāore ngā pānga o te hangarau i te taha whakahaere: E whakaatu ana ngā rōpū taiao i te kaha ki te whakaiti i te para hiko mā te 220,000 tana ia tau mā te whakamahi i ngā tohu taiao ka pirau i roto i ngā rā 90.
