A wearable article, a system, and methods include a structural material configured to enable the wearable article to the worn on a body, a piezoelectric generator, positioned with respect to the structural material in a configuration to be flexed to output a voltage, a data translator, coupled to the piezoelectric generator, configured to output electronic data based on the voltage, and an electronic data storage, coupled to the data translator, configured to store the electronic data from the data translator.

A housing of an incline adjuster may include a medial fluid chamber in fluid communication with a lateral fluid chamber through a serpentine transfer channel. The housing of the incline adjuster may include channels through which electrorheological fluid may be injected into the chambers. A method of filling an electrorheological fluid structure may include introducing electrorheological fluid into an interior volume of a housing. The electrorheological fluid within the housing may then be subjected to a sub-atmospheric pressure. Subsequently, the interior volume may be sealed relative to an exterior of the housing.
