Siyajabula ukwethula indwangu yethu yokunyathelisa ekhethekile kuwe.Le nto yakhiwe kusetshenziswa indwangu yesikhumba sepentshisi njengesisekelo sayo kanye nokwelashwa okuzwela ukushisa kungqimba lwangaphandle.Ukwelashwa okuzwelayo ekushiseni ubuchwepheshe obuhlukile obulungisa izinga lokushisa lomzimba womuntu oyifakile, bubagcine benethezekile kungakhathaliseki isimo sezulu noma umswakama.
Indwangu yethu ye-Thermochromic (ezwela ukushisa) yenziwa yenzeka ngokusebenzisa intambo egoqeka ibe yinqwaba eqinile uma kushisa, idale izikhala kwindwangu yokulahlekelwa ukushisa.Ngakolunye uhlangothi, lapho indwangu ibanda, imicu iyanda enciphisa izikhala ukuze ivimbele ukulahlekelwa ukushisa.Izinto ezisetshenziswayo zinemibala eyahlukene, namazinga okushisa okwenza kusebenze okuthi lapho izinga lokushisa likhuphuka ngaphezu kwezinga elithile, upende ushintsha umbala, ukusuka komunye umbala ukuya komunye noma ukusuka kombala kuye kokungenambala (okumhlophe okukhazimulayo).Inqubo iyahlehla, okusho ukuthi uma kushisa noma kubanda, indwangu ibuyela embala yayo yasekuqaleni.
