An insole for controlling and adjusting the temperature of the foot. The insole includes a first heat conductive layer made of fabric, a second heat insulating layer comprising a Peltier cell. The Peltier cell includes a first surface and has a predetermined polarity such that, when the Peltier cell is on, the first surface is heated or cooled. A third heat dissipating layer includes an accelerometer and a logic control unit connected to the accelerometer and to the Peltier cell. The insole further includes a first flexible printed circuit configured to measure the temperature of the foot, through at least a first temperature sensor and the temperature of the first surface of the Peltier cell, through a further first temperature sensor.

An article and system for regulating temperature in footwear. Thermal footwear may include a power generation layer, a thermocell layer, and an accessory layer. The power generation layer may be constructed of an actuator materialfor example, a dielectric elastomerwhich may generate an electric current when compressed or decompressed. The thermocell layer may be configured to either warm or cool a user's foot, and may be reversible by being removably coupled to the power generation layer. The accessory layer may include other components; for example, an integrated circuit chip for power transmission to an external device may be included.

In one example, we describe a method and system for supporting the sides of the ankle, tight, with a solid hard material, like hard plastic, and making the foot and ankle to act together as one piece, to make the foot more stable and comfortable. Or, we can do this as an add-on for a shoe, later on, to insert as an extra, for the same function. Or, we can do it for any types of shoes. Different structures and components or variations are also discussed.

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.
