Abstract
An embedded sensor apparatus for enabling wireless signal transmission while protecting an embedded sensor is disclosed. In various embodiments, an embedded sensor apparatus may comprise a substrate with a cavity, a wireless sensor embedded in the cavity of the substrate, a protective cover coupled to the wireless sensor, and a ferrite layer covering the protective cover. Further, the embedded sensor apparatus may comprise an electromagnetic reflector coupled between the wireless sensor and the substrate. In addition, the ferrite layer may be a ferrite plug, a deposited ferrite layer, or a combination thereof. Furthermore, in various embodiments, covering the protective cover with the ferrite layer may comprise depositing the ferrite layer on the protective cover using a cold spray process. In another embodiment, covering the protective cover with the ferrite layer may comprise depositing the ferrite layer on the protective cover using a thermal spray process.
