An electronic data storage, coupled to the voltage sensor, is configured to store voltage profile information based on the sensor data. A comparator, coupled to the electronic data storage, is configured to identify a change in the voltage profile information over time. The wireless transmission circuit is configured to transmit data indicative of a physical status of the article of footwear based on the change in the voltage profile information over time.

Provided is an insole-type electronic device wherein the electronic module is not susceptible to impact and/or load due to walking or running. The insole-type electronic device is an electronic device wherein an electronic module has been incorporated in the insole that is laid on the midsole of a shoe and contacts the sole of the foot. The insole-type electronic device has an insole body with the shape of a normal insole. Said insole body has a heel-protecting part that extends upward from the back end of the heel section of the insole body along the perimeter of the back end of the heel section. Additionally, the insole-type electronic device has an electronic module that is housed in the heel-protecting part.

Systems and methods for generating nitric oxide are disclosed. A nitic oxide (NO) generation system includes at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas; and a controller configured to regulate the amount of nitric oxide in the product gas produced by the at least one pair of electrodes by utilizing duty cycle values of plasma pulses selected from a plurality of discrete duty cycles to produce a target rate of NO production based on an average of discrete production rates associated with each of the plurality of discrete duty cycles.

A wearable system, such as a footwear system, can employ a generator. The generator can be powered by human movement, such as movement of knee as a person walks or runs. When the knee resets, it can be desirable to have a relatively equal gear ratio to achieve near natural movement. Conversely, it can be desirable to have a high gear ratio when the knee pushes off to achieve high generator rotation to produce a high amount of power. This can be achieved with employment of a wearable planetary gear set configuration In practicing this wearable planetary gear set, torque can be provided from the source (e.g. human ankle joint) when power negative and not at other times during a movement cycle, meaning energy can be harvested from the walking motion without inducing additional burden to the device wearer.

In an example, a wearable article includes a nonwoven textile sheet having a first portion and a second portion contiguous with the first portion. The first portion has a first density and a first modulus of elasticity. The second portion has a second density less than the first density and has a second modulus of elasticity less than the first modulus of elasticity. The first portion is shaped differently than the second portion as an integral implement of the wearable article. A method of manufacturing a wearable article may comprise thermoforming the first portion while the second portion contiguous with the thermoformed first portion is not thermoformed.
