Abstract
A helmet and/or helmet liner including at least one compartment, chamber, bladder, or internal sipe. The at least one compartment, chamber, bladder or internal sipe includes a media with at least one magnetorheological liquid for use to absorb shock or change sliding resistance by changing an alignment of metal particles of the magnetorheological fluid to alter a flow resistant structure. The helmet and/or helmet liner also includes an electronic control system that controls the flow resistance of the magnetorheological liquid of the at least one chamber compartment or bladder by changing an alignment of metal particles of the magnetorheological liquid to alter a flow resistant structure included in the at least one inner compartment, chamber or bladder. The helmet and/or helmet liner may also include a second compartment, chamber or bladder surrounding another compartment, chamber or bladder, with an internal sipe located between surfaces thereof.
