A power collector structure connected to a base is repetitively deformed or bent. The power collector structure is bar-like, and is connected to the base in an essentially rigid manner. A power collector for converting mechanical energy to electric power is connected to the power collector structure.

The present invention provides a power generating device, comprising the first shell, the sensor module, the second shell, the magnetic module, the cover and the elastic element. The sensor module is disposed in the first hollow portion. The second shell is disposed on the first shell. The magnetic module is disposed on the first fixture portion of the second shell. The cover is disposed on the external surface of the second shell, and the convex portion penetrates through the hole and holds the magnetic module in the first fixture portion. The elastic element is disposed between the first shell and the second shell. When the power generating device takes the external force, the second shell and the first shell do the relative movement; meanwhile, the first magnetism element of the magnetic module slides through the direction of the external force in the first slide gap and the induced current is generates on the induction coil by the change of the magnetic flux.

A method and apparatus for generating thermal energy (heat) from human locomotion is proposed and used to provide heating of the user's footwear. The apparatus takes the form of a pair of flexible, liquid-filled chambers connected by an energy-generating tube. One chamber is located in the heel region of a footwear insole, with the other in the toe region, such that as a person walks, the liquid moves back and forth within the tube. This movement is used to also move an energy-producing element (either an electromagnetic arrangement or viscous liquid) back and forth within the tube and convert the captured human locomotion energy into thermal energy, thus warming the footwear.

A shoe includes a sole, an actuator and a transducer. The actuator is mounted on one side of the sole. The transducer is mounted within the sole and includes a micro-motor, a link structure and a heater. The link structure is positioned between the micro-motor and the actuator and configured to move the micro-motor to generate electric energy. The heater is electrically coupled to the micro-motor and configured to convert the electric energy provided by the micro-motor to heat. When the actuator deforms or restores its deformation, the link structure moves thereby enabling the micro-motor to generate electric energy for the heater.

A step-counter device detects and counts user steps. The device includes a transducer configured to generate an electrical transduction signal in response to user stepping. An energy-scavenging system is coupled to the transducer to generate a power supply voltage in response to the electrical transduction signal. A processing unit is powered by the power supply voltage. The processing unit is further configured to sense the electrical transduction signal and determine whether a user step has occurred and in response to that determination increment a step counter.

The present invention is footwear designed to produce electric power based on the movement of a wearer of the footwear. The footwear includes a kinetic energy generator integrated into the heel of the footwear. A rotor is included in the kinetic energy generator and is adapted to spin in response to the movements of the footwear. A shaft is coupled to the rotor and is configured to perform reciprocal movements to spin the rotor and generate electricity. A charging port is disposed at the rear of the footwear and is configured to receive a power cord such as a USB cable for charging electronic devices. The kinetic energy generator is lightweight and compact and maintains the comfort and usability of the footwear while generating electrical power. The footwear is coupled to a smartphone application for displaying current location, heat map, and electric power generation information of the footwear.

Disclosed herein is a self-generation shoe using magnetic induction. The self-generation shoe includes a self-generation unit which is configured to generate electromotive force using magnetic induction, a rectifier circuit which converts electromotive force generated from the self-generation unit into constant voltage, and a charging circuit which charges the constant voltage output from the rectifier circuit. The self-generation unit includes a coil bobbin and a permanent magnet. The coil bobbin has a hollow pipe structure and protrudes downward from an upper surface of the chamber. A coil is wound around the outer surface of the coil bobbin. The permanent magnet protrudes upward from the lower surface of the chamber and is inserted into or removed from the coil bobbin depending on contraction or expansion of the chamber.
