For example, a PVC sheet sandwiched between two films of rigid polyester featuring slits of different sizes contracts
The PVC becomes deformed creating different angles where the edges of the polyester films press against each other.
The prototype consists of copper wires insulated with PVC tubes. On one end, the copper wires are hooked up to an external analyzer and on the other end,
the engineers used coils of copper wires insulated with PVC tubing. At one end of this arrangement, the wires terminate at a receiver and analyzer,

The middle layer always consisted of polyvinyl chloride, a plastic commonly used in plumbing pipes, which contracts when heated.
For example, they added the nanosheets to a film of polyvinyl chloride, thereby doubling its strength and increasing its tensile toughness sixfold.
