An apparatus comprising an energy-harvesting means and a radio frequency (RF) communication means. Said energy-harvesting means is configured to capture mechanical energy from the human motion and convert it to useful electrical energy. Said RF communication means is configured to establish RF communication with the mobile electronic devices in its vicinity using low-power, short-range RF communication signals. Said RF communication means is further configured to retransmit the information received through said short range RF communication signals using high-power long-range communication signals, thereby allowing said mobile electronic devices to establish a long-range RF communication with the remote recipient substantially utilizing the energy derived from the energy-harvesting means rather than the energy predominantly derived from said mobile electronic devices themselves |
