Abstract
Systems and methods for developing a composite material are disclosed. The system can include a plurality of particles and a plurality of polymers. The plurality of particles can generate mechanical force in response to changing relative humidity, and the plurality of filaments can transfer the mechanical force throughout the composite material, such that the mechanical force changes a shape of the composite material reversibly and repeatedly.
Claims20
A composite material comprising:
- a plurality of particles configured to generate mechanical force in response to a changing relative humidity;
- and
- a plurality of polymers enmeshed with the plurality of particles and configured to transfer the mechanical force throughout the composite material,
- such that the mechanical force changes a shape of the composite material reversibly and repeatedly.
A method for fabricating a composite material, comprising:
- mixing a plurality of particles and a plurality of polymers to make a solution, wherein the plurality of particles is configured to generate mechanical force in response to a changing relative humidity;
- and
- drying the solution to produce the composite material, wherein the plurality of filaments is enmeshed the plurality of particles and configured to transfer the mechanical force to the composite material,
- such that the mechanical force changes the shape of the composite material reversibly and repeatedly.
A method of fabricating a fabric actuator, comprising:
- mixing a plurality of particles and a plurality of polymers to make a solution, wherein the plurality of particles is configured to generate mechanical force in response to a changing relative humidity;
- drop-casting the solution onto a TPU film;
- drying the drop-casted TPU film, wherein the plurality of filaments is enmeshed the plurality of particles and configured to transfer the mechanical force to the TPU film, such that the mechanical force change the shape of the composite material reversibly and repeatedly;
- and
- adhering the dried TPU film to a polyester fabric to form a fabric actuator.
