Izinzwa zengcindezi, njengengxenye esemqoka ezenzakalelayo zezimboni kanye nemishini ehlakaniphile, dlala indima ebaluleke kakhulu. Kungakuqonda ngokunembile futhi kuguqule isinali yengcindezi yento ephakeme ibe isibonakaliso sikagesi esilinganiswayo futhi esidluliselwe esidlulelekile, ukuze kufinyelelwe ukuqapha kanye nokulawulwa kwengcindezi. Noma ngabe kubhekisisa isimo sokusebenza kwemishini ngomugqa wokukhiqiza izimboni noma izinguquko zokuhlola umfutho wegazi womuntu emishini yezokwelapha, izinzwa zengcindezi zidlala indima ebalulekile.

Umgomo wayo wokusebenza ususelwa ezinhlotsheni ezahlukahlukene zomzimba ezifana nomphumela we-piezoresustive, umphumela we-piezoelectric noma ushintsho lwe-capsoelect, futhi ukhombisa ingcindezi ngoshintsho oluncane lwesakhiwo noma izinguquko zempahla ezibonakalayo. Ukunemba okuphezulu, ukuqina okuphezulu, ukuphendula okusheshayo nokuguquguquka okuhle kwemvelo kuyizimpawu eziphambili zezinzwa zesimanje zengcindezelo. Ngokuthuthuka okusheshayo kobuchwepheshe obufana ne-Intanethi yezinto kanye nedatha enkulu, izinzwa zengcindezi zihlanganiswa kancane kancane kwizimo ezibanzi zezicelo, zisiza ukufezekisa ukukhiqizwa okuqondayo nokuzenzakalelayo, futhi kufaka isandla enqubekela phambili yesayensi kanye nentuthuko yezobuchwepheshe kanye nasekuthuthukisweni komphakathi.
