| 摘要 |
An embedded sensor apparatus (100;200;300;400) for enabling wireless signal transmission while protecting an embedded sensor (103) is disclosed. In various embodiments, an embedded sensor apparatus (100;200;300;400) may comprise a substrate (101;301;401) with a cavity (102), a wireless sensor (103) embedded in the cavity (102) of the substrate (101;301;401), a protective cover (104) coupled to the wireless sensor (103), and a ferrite layer (105;205;305;405) covering the protective cover (104). Further, the embedded sensor apparatus (100;200;300;400) may comprise an electromagnetic reflector (106) coupled between the wireless sensor (103) and the substrate (101;301;401). In addition, the ferrite layer (105;205;305;405) may be a ferrite plug (205), a deposited ferrite layer (105;305;405), or a combination thereof. Furthermore, in various embodiments, covering the protective cover (104) with the ferrite layer (105;205;305;405) may comprise depositing the ferrite layer (105;305;405) on the protective cover (104) using a cold spray process. In another embodiment, covering the protective cover (104) with the ferrite layer (105;205;305;405) may comprise depositing the ferrite layer (105;305;405) on the protective cover (104) using a thermal spray process. |
