Closed-loop fluidic regenerative system and active compression band, apparel, device, footwear and method

A wearable assistive device comprising:

• a fluidic transducers module comprising at least one fluidic transducer, wherein the fluidic transducers module is operable to receive a fluid under pressure and in response to operate the at least one fluidic transducer;
• a fluidic regeneration module operable to receive and to pressurize the fluid responsive to mechanical interaction with the fluidic regeneration module;
• and
• a fluidic transportation module coupled to transport the fluid between the fluidic transducers module and the fluidic regeneration module;
• wherein:
• the fluidic regeneration module comprises at least one fluidic regeneration chamber to contain the fluid, wherein the at least one fluidic regeneration chamber is mechanically compressible to pressurize the fluid in the at least one fluidic regeneration chamber to transport the fluid under pressure to the fluidic transducers module via the fluidic transportation module;
• and
• the wearable assistive device further comprises an energy return mechanism operable to return the fluid from the fluidic transducers module to the fluidic regeneration module via the fluidic transportation module when the at least one fluidic regeneration chamber is decompressed wherein the at least one fluidic regeneration chamber comprises an elastic wall defining an interior volume of the at least one fluidic regeneration chamber is compressible to decrease the interior volume, thereby to pressurize the fluid to transport the fluid under pressure to the fluidic transducers module via the fluidic transportation module;
• and is operable to rebound to increase the interior volume of the at least one fluidic regeneration chamber when the at least one fluidic regeneration chamber is decompressed, thereby to return the fluid from the fluidic transducers module to the fluidic regeneration module via the fluidic transportation module .
