Lub massager yog ib qho khoom siv kev noj qab haus huv thiab kev noj qab haus huv tsim los ntawm cov hauv paus ntsiab lus los ntawm physics, bionics, thiab tsoos suav tshuaj. Los ntawm kev siv electromagnetic vibration lossis mechanical rotation los simulate manual massage techniques-xws li kneading and percussive tapping- nws pab txo cov leeg qaug zog thiab txhawb cov ntshav ncig. Nws cov thawj pawg muaj xws li electromagnetic, vibratory, thiab infrared hom; cais los ntawm thaj chaw thov, lawv suav nrog cov cuab yeej tshwj xeeb rau lub caj dab, xub pwg, ko taw, thiab lwm yam hauv lub cev, npog ob qho tib si hluav taws xob thiab tsis yog- cov khoom siv fais fab.
Lub hauv paus chiv keeb ntawm cov cuab yeej no yog nyob rau hauv fusion ntawm niaj hnub electronics technology nrog ib txwm massage kho. Thaum ntxov iterations feem ntau tshwm sim los ntawm ib qho kev vibration muaj nuj nqi, tab sis cov tshuab tau hloov zuj zus mus rau hauv cov khoom ntse ntse uas sib xyaw ua haujlwm nyuaj xws li acupuncture stimulation thiab *gua sha*. Nyob rau hauv cov nqe lus ntawm kev ua lag luam dynamic, Tuam Tshoj tus massager xa tawm nyob rau hauv 2008 mus txog 174 lub teb chaws thiab cheeb tsam, lub hom phiaj feem ntau tsim kev lag luam ntawm cov teb chaws Europe, North America, thiab Asia. Tsav los ntawm kev txhim kho thev naus laus zis, cov khoom lag luam tau nce zuj zus mus rau kev ua haujlwm me me thiab hauv tsev- siv cov qauv tsim, thaum sib koom ua ke nrog kev txiav- ntug teb xws li microelectronics thiab biomedical engineering.
