Feidhmchlár Fetal Doppler:
Is gléasanna Doppler ultrafhuaime é doppler féatais a úsáidtear chun buille croí féatais a bhrath. Seolann an taiscéalaí Doppler tonnta fuaime ardmhinicíochta isteach sa chorp. Níor cheart é a mheascadh le radaíocht. Nuair a léiríonn seasamh an chroí féatais na dtonnta ultrafhuaime, athraítear minicíocht na dtonnta. Faigheann an Doppler féatais na tonnta fuaime frithchaite agus úsáideann sé an coincheap Doppler Effect chun an t-athrú minicíochta a ríomh agus soláthraíonn sé ionsamhlú inchloiste ar bhuille an chroí. Déantar an fhuaim seo a aimpliú trí na cluasáin ansin. Tá Dopplers féatais thart ar feadh na mblianta fada, agus níor tuairiscíodh aon éifeachtaí díobhálacha riamh óna n-úsáid.
Ábhar PZT:
- Tá iompar dúbailte glactha agus tarchurtha ag criadóireacht piezoelectric PZT4, le híogaireacht níos airde agus caillteanas tréleictreach níos ísle.
- PZT5 Tá comhéifeacht cúplála leictrimheicniúla níos airde ag criadóireacht piezoelectric, an tairiseach tréleictreach measartha agus íogaireacht níos airde.
- PZT8 Tá dea-mhaoin piezoelectric ag criadóireacht piezoelectric de chineál tarchurtha ardchumhachta, neart meicniúil ard, réimse ard-coercive, caillteanas tréleictreach íseal i réimsí láidre.
