Tepana piezoelectriche mea hanga mai i tētahi VPM (Versatile Piezoelectric Module) kua pēhia ki roto i tētahi whare whakarewa pakari. Ko te waeine piezoelectric he wāhanga e whakaputa ana i te ngaohiko hei whakautu ki te ahotea ā-pūkaha. Mā te mahi i runga i te "pānga piezoelectric," ka whakaputa te pēhanga ā-pūkaha (hei tauira, te pēhanga mai i te maihao) i te ngaohiko e whakatuwhera ana, e kati rānei i te ara iahiko.
Nō reira, ina pēhia, ka puta he huringa ngaohiko e rite ana i te rauemi tioata piezoelectric ka tukuna ki te papa ara iahiko mā te rauemi hononga ara iahiko, e whai ana i te katinga o te pana whakapā maroke, e whakawhirinaki ana ki te pānga piezoelectric hei whakaputa i tētahi pātere āhua "ki" poto ka rerekē te roa i runga i te nui o te pēhanga e pā ana.
Ina pēhia ki te pēhanga teitei ake, ka puta hoki ngā ngaohiko teitei ake, roa ake hoki. Mā te whakamahi i ngā ara iahiko me ngā retireti tāpiri, ka taea te whakaroa ake i tēnei pātere, te whakarerekē rānei i te pātere āhua "kā" ki te pātere āhua "weto".
I taua wā anō, he pūnga iahiko anō hoki e pupuri ana i te utu, e āhei ai te whakaroa i te roa o te ora o te pākahiko. Ko te pāmahana mahi ka taea te noho i waenga i te -40ºC me te +75ºC. Ko te āhuatanga matua ko te kore o ngā wāhanga nekeneke, pērā i ngā puna, i ngā rīwhi rānei, e wehewehe ana i a ia i ngā pana miihini tuku iho.
Nā te hanganga kotahi-wahi o te pana, ka tutuki te hiri mahi teitei (IP68 me te IP69K) ki te makuku me te puehu, ka ātete ki te kino, ki ngā āhuatanga o waho rānei. E ai ki te whakatauranga mō te 50 miriona mahi, he ātete ake ki te ru, he ātete wai, he pakari ake i ngā pana miihini.
Nā ēnei āhuatanga, kāore he tūponotanga o te pakaru me te haehae, ka roa ake ai te ora o ā rātou mahi, ā, kua kitea ngā tono i roto i ngā momo ahumahi. Ka taea te whakamahi i roto i te kawe waka, te tiaki whenua, te tukatuka kai me ngā wharekai, ngā waka moana me ngā waka papai, te hinu me te hau, me te ahumahi matū.
