Reprogrammable Morphing Sheets Via Magnetically Controlled Folding and Articulated Components

A system, the system comprising:

• a magnetic write head,
• the magnetic write head being configured to define a magnetic pattern on a magnetizable substrate sheet;
• and
• a magnetic coil,
• the magnetic coil being configured to apply a magnetic field to a magnetizable substrate sheet so as to effect folding of the magnetizable substrate sheet.

A component, comprising:

• a plurality of articulable segments arranged circumferentially so as to define a first collapsable frustum and a second collapsable frustrum,
• each of the first collapsable frustum and the second collapsable frustum having a base,
• the first collapsable frustum and the second collapsable frustum extending away from their respective bases and converging toward one another,
• the first collapsable and second collapsable frustum converging at a plane and the component defining therein an opening at the plane,
• the component configured such that the first collapsable frustum and second collapsable frustrum are collapsable toward one another so as to attain one or more stable collapse states,
• the opening attaining at a given stable collapse state a cross-sectional dimension associated with that stable collapse state, and
• the greater a degree of collapse of the first collapsable frustum and the second collapsable frustum, the smaller the cross-sectional dimension of the opening.
