Ho na le mefuta e mengata ea li-sensor tsa khatello, tse ka aroloang likelellong tsa khatello ea maikutlo, li-senters tsa khatello le khatello e felletseng tsa khatello ho latela mofuta oa khatello ea liteko. Har'a bona, sensor se boima sa khatello ea khatello ea mathata se sebelisoa haholo lefapheng la lipalami. Molao-motheo o mong le o mong o na le melemo le boholo ba kopo, joalo ka li-sensortic tsa piezoretric tsa ho bona hore na Pizeoelectric li sebelisa lipontšo tsa Voltage.
