1. An apparatus for generating energy to supplement an ambient environment, the apparatus comprising:
- a wireless sensor comprising an energy storage device;
a wireless energy generator; and
a wireless interface supporting a first wireless communication channel and a second wireless communication channel, wherein;
the wireless energy generator sends a first wireless signal to the wireless sensor over the first wireless communication channel;
the wireless sensor extracts energy from the first wireless signal;
the wireless sensor sends a second wireless signal to the wireless energy generator via the second wireless communication channel, the second wireless signal indicative of energy requirements of the wireless sensor;
the wireless energy generator determines a level of the first wireless signal based on the indicated energy requirements of the energy storage device;
when operating in a continuous mode and the wireless sensor is discharging, the wireless energy generator increases the level of the first wireless signal; and
when operating in the continuous mode, the wireless sensor is charging, and a charge level of the energy storage device of the wireless sensor is not below a predetermined threshold, the wireless energy generator decreases the level of the first wireless signal.
