Implantable wireless device for transmitting data

An implantable wireless device for transmitting data comprising:

• an external control device comprising:
• a phase shift keying (PSK) modulator receiving digital data and an alternating current (AC) carrier signal and using the AC carrier signal to modulate the digital data into a phase shift keying (PSK) modulation signal, and the digital data have a plurality of time points that binary data change;
• and
• a first wireless transmission coil whose quality factor is larger than 100, and the first wireless transmission coil is electrically connected to the phase shift keying modulator;
• and
• an internal processing device implanted in a physiological tissue and comprising:
• a second wireless transmission coil whose quality factor is larger than 100;
• a phase-lock loop (PLL)-based phase shift keying demodulator electrically connected to the second wireless transmission coil, receiving the phase shift keying modulation signal through the first wireless transmission coil and the second wireless transmission coil, and obtaining a ripple voltage signal according to the phase shift keying modulation signal, and the ripple voltage signal decreases from a fixed voltage value at each of the plurality of time points and then increases to the fixed voltage value, and the phase-lock loop-based phase shift keying demodulator demodulates the ripple voltage signal into the digital data;
• and
• an alternating current (AC) to direct current (DC) converter electrically connected to the second wireless transmission coil, receiving the phase shift keying modulation signal through the first wireless transmission coil and the second wireless transmission coil, and converting the phase shift keying modulation signal into a supplying direct current voltage.
