    摘要: A sole for footwear capable of recovering part of the energy produced during deambulation including: at least one energy harvesting means, including: a tubular body, fixed in use, having a first and a second end and a movable part slidable in the tubular body; the energy harvesting means being provided, in use, for generating electrical energy following the sliding of the movable part with respect to the tubular body that is fixed in use, during the deambulation; at least one actuator group for the energy harvesting means, including at least one fluid-dynamic circuit including: at least one first and one second tank including a fluid, the first tank being housed at a rear area of the sole and the second tank being housed at a front area of the sole; at least one first and one second joining conduit in fluid connection between the first tank and the first end of the at least one tubular body, and the second tank and the second end of the tubular body, respectively, where, the first tank has a configuration in plan view which is substantially elongated and curved.

    摘要: A kinetic energy generator, system and method of transmitting data are described. The kinetic energy generator includes a piezoelectric element that receives kinetic energy initiated by a user, a rectifier connected with the piezoelectric element that rectifies voltage from the piezoelectric element, a capacitive system of capacitors formed from different materials connected with the piezoelectric element through the rectifier, a short-range transceiver connected with the capacitive system and activated in response to energy storage in the capacitive system reaching a threshold level, and a non-volatile memory that provides at least some of the data transmitted by the transceiver in response to a request from the transceiver. Below an inflection point, the capacitive system stores more energy than one system of one capacitor type and less energy than another system of another capacitor type arranged in the same manner as the capacitive system, and the reverse above the inflection point.
