Abstract: Various examples of methods, systems, and apparatus are provided for monitoring using an improved mouth guard apparatus. In one example, a battery-free diagnostic mouth guard includes a biting force-voltage transducer comprising a piezoelectric film; a compact resonance tank comprising a wireless sensor; and a transmitting antenna for transmitting sensing data. A piezo-voltage from the biting force-voltage transducer can bias a varactor diode loaded on the wireless sensor whose response frequency is tuned due to a capacitance change of the varactor diode. In some implementations, an external processing equipment can wirelessly detect a frequency shift of the varactor diode integrated resonator. In another example, a method includes detecting a biting force via a biting force-voltage transducer; biasing a varactor diode with a voltage from the transducer; tuning a response frequency of a split ring resonator using a capacitance change of the varactor diode; and emitting sensing data at the response frequency.

Abstract: Various examples are provided for a helix antenna with dual functionality, in one embodiment, among others, a helix antenna includes a flexible substrate and a copper trace disposed on a side of the flexible substrate at a tilting angle (Θ). Turns of the helix antenna are formed from the copper trace by wrapping the flexible substrate. In another embodiment, a system includes a helix antenna, a radio frequency (RF) communication circuit coupled to a first end of the helix antenna, and a low frequency (LF) power transmission circuit coupled to the first end of the helix antenna. The RF communication circuit can process RF signals received by the helix antenna and the LF power transmission circuit can regulate LF voltage induced in the helix antenna.
