A cell that remembers its shape

Most machines that change shape keep paying to stay changed. A motor holds position by drawing current. A pneumatic support holds by keeping air pressure up. Turn the supply off and the shape goes with it.

A ShapeCell works the other way. It is a compliant mechanism with two mechanically stable geometries, separated by an energy barrier. Pushed over the barrier, it settles into the other geometry and stays there. The geometry itself does the holding.

ArchitectureDescribes the design. Not a measured Nanoshape result.

A state element, not an actuator

That makes a ShapeCell closer to a bit of memory than to a motor. It does not move continuously. It has states, and something outside it decides which one it is in.

In Proteus, that something is the Shape Dock: the external field source and controller. Proteus must be docked to reconfigure. The dock selects cells, drives each across its barrier, and lets it latch. Once latched, Proteus holds its geometry off-dock at zero power.

Many small decisions, one shape

One cell is a binary choice. Thousands of cells in one connected body give a surface whose form is the sum of their states. The Shape Compiler is the layer that turns intent into that sum: a geometry model, then a state map, then a verified physical form.

The forward direction, from a state map to the shape it produces, is the part we are calibrating now. The reverse direction, finding the state map that best produces a target shape when the cell count is large, is inverse design. At large cell counts it remains open, and it is one of the things the program is built to answer.

Why it matters first in two places

A cell that holds without power suits work that sets a shape and then waits: a deployable structure stowed until it is needed, or a tooling surface held for the length of a production run. Those are the two places we start.
