  • Scientists constructed the membrane using multilayered triboelectric nanogenerators, nanowires, and polystyrene.
  • Allows for power to be generated and stored for later use.
  • The fabric is flexible, breathable, lightweight, and durable.

According to a study in Nano Energy, scientists have created a triboelectric fabric that can generate power from body motion. The fabric possesses qualities reminiscent of materials used in modern clothing, such as flexibility and breathability.

The scientists constructed the membrane using multilayered triboelectric nanogenerators, nanowires, and polystyrene. Power is generated by the nanogenerators identifying and capitalizing on the motion of two different materials making contact then moving apart. The nanowires and polystyrene combat power dissipation and provide a layer for storing generated energy.

Electrospun fibers (such as triboelectric nanogenerators) were selected for the fabric’s construction due to their durable and lightweight properties. Furthermore, they’re compact and safe for humans to wear, making them an optimal choice for developing wearable technology. Researchers are working towards improving the fabric by increasing charge capacity and energy generation efficiency.

Body motion power generators have been researched and previously attempted, but many efforts were met with issues such as stiffness, lack of comfort, and insufficient breathability. Additionally, most triboelectric-based devices lack the presence of a polystyrene membrane, reducing its ability to collect and store any generated power.

The newly developed triboelectric fabric circumvents many obstacles associated with body motion power generators, creating an exciting prospect for the future of wearable devices.
