Problems solved by technology
The frequent use of these devices may require a significant amount of power, which may easily deplete the batteries attached to these devices.
Therefore, a user is frequently needed to plug in the device to a power source, and recharge such device.
Such an activity may be tedious and may represent a burden to users.
However, such an activity may render electronic devices inoperable during charging.
Solar-powered battery chargers are also known, however, solar cells are expensive, and a large array of solar cells may be required to charge a battery of any significant capacity.
Assuming that the transmitted signal has an efficient reception at three centimeters from the EM transmitter, receiving the same signal power over a useful distance of three meters would entail boosting the transmitted power by 10,000 times. Such power transmission is wasteful, as most of the energy would be transmitted and not received by the intended devices, it could be hazardous to living tissue, it would most likely interfere with most electronic devices in the immediate vicinity, and it may be dissipated as heat.
However, even when the device is located, efficient transmission is not guaranteed due to reflections and interference of objects in the path or vicinity of the receiving device.
In addition, in many use cases the device is not stationary, which is an added difficulty.
