1. A method of using wirelessly transmitted sound waves to provide usable power to a temperature regulation circuit embedded in clothing or smart fabrics, the method comprising:

  • receiving wirelessly transmitted sound waves (SW) from a pocket-forming transmitter having a SW integrated circuit, transducer elements, a microprocessor, and first communication circuitry, wherein;

    the wirelessly transmitted sound waves converge in 3-d space at predetermined locations within a predefined range of the transmitter to form pockets of energy, andthe wirelessly transmitted sound waves are received by one or more sensor elements of a receiver that is embedded in clothing or smart fabric, the receiver including second communication circuitry and a connection to a temperature regulation circuit;

    converting, by the receiver, energy from at least some of the wirelessly transmitted sound waves forming the pockets of energy into usable power that is provided to the temperature regulation circuit;

    regulating, by the temperature regulation circuit, a temperature of the clothing or smart fabric at least in part by using the usable power.
