[1] wave (mmWave) sensing bụ usoro na-enweghị njikọ nke iji mmWave radar sensors iji tụọ mmegharị, ọsọ, na akụkụ dị ka obere dị ka akụkụ nke milimita. Usoro [2] chọrọ ihe mmetụta radar mmWave iji zipu ma nata pulses nke millimeter electromagnetic wave energy, na-achọpụta ihe ndị a na-achọ na mmegharị site na ntụgharị ọ na-enweta azụ. Ihe n[3] ọzọ dị ka ndị na-agbanwe agbanwe, ndị na-emepụta mgbaàmà na teknụzụ ndị ọzọ a na-etinye n'ime ya na-emepụta ihe ọhụrụ ma melite arụmọrụ nke usoro ahụ. Ngwa n[4] dị ugbu a maka teknụzụ a gụnyere nsuso mmegharị mmadụ na anụmanụ, nchọpụta ọnụnọ mmadụ, na nchọpụta nke ihe ịrịba ama dị mkpa maka ojiji n'ofe ụgbọ ala, ihu igwe, ahụike na ụlọ ọrụ ahụike anụ ụlọ ma na-abụkarị ihe ọzọ maka teknụgbọala a na-eyi maka otu ojiji ahụ.

N'iji ya tụnyere teknụzụ mmetụta site na iji redio ndị ọzọ na electromagnetic spectrum dị ka infrared ma ọ bụ ultra-wideband, mmWave na-eji 30 ruo 300 gigahertz (GHz). Ihe mmetụta mmWave [5]-eji 24-, 60- na 77-GHz nke ọ bụla nwere uru nke ha maka ngwa ụfọdụ.

Ụgbọala[dezie | dezie ebe o si]

Enwere ike iji sensing MmWave n'ime ụgbọ ala iji melite ọrụ nchekwa nke ọkwọ ụgbọ ala na ndị njem.[6] Uru ndị ama ama nke iji teknụzụ mmWave n'ime ụgbọ ala dabere na ikike ya ịrụ ọrụ nke ọma na oghere nwere obere ọkụ yana obere ọhụhụ. MmWave sensing nwere ike banye n'ime ihe ndị dị ka plastik, textiles, na ugegbe, na-eme ka ọ bụrụ enweghị kọntaktị.[6] [7]

Ngwa ndị na-adịbeghị anya maka mmWave sensing ụgbọ ala gụnyere:

  • Nchọpụta nke ndị bi na ya
  • Nchọpụta ọnụnọ ụmụaka (CPD)
  • Ihe ncheta oche
  • Ntinye ikuku kachasị mma
  • Nlekọta nke ihe ịrịba ama dị mkpa nke onye ọkwọ ụgbọala [8]

Ndụ enyere aka na nlekọta ndị agadi[dezie | dezie ebe o si]

Enwere ike iji mmetụta MmWave n'ụlọ na ebe a na-elekọta ndị agadi iji nyere ndị agadi aka, ndị mmadụ n'otu n'otu na-eme agadi, na ndị nlekọta. Iji teknụzụ mmWave anaghị akpa ike n'ihi na ọ naghị eji igwefoto ma ọ bụ igwe okwu maka ngwa ya, ọ chọghịkwa ka ndị ọrịa jiri ngwaọrụ wearable maka nsochi.

Ebe Obibi[dezie | dezie ebe o si]

N'ịbụ nke e jikọtara n'ime ngwa maka ọnụnọ na nchọpụta obibi, enwere ike itinye mmWave sensing na ụlọ smart iji mee ka ụlọ na-arụ ọrụ n'onwe ya n'achọghị teknụzụ ma ọ bụ igwefoto.Ngwa gụnyere:

  • Nchọpụta nke ọkwa mmiri nke ụlọ mposi[9]
  • Nnyocha nke apnea ụra[10]

[11] ndị ọzọ maka mmWave sensing gụnyere nlekota anụ ụlọ, ebe enwere ike iji teknụzụ ahụ soro ma nyochaa ihe ịrịba ama dị mkpa nke anụmanụ iji kọwaa mmetụta anụ ụlọ.
