Energy Harvesting

Fiber-based electronics are expected to play a vital role in next-generation wearable electronics. Woven into textiles, they can provide higher durability, comfort, and integrated multi-functionality. A research team has developed a stretchable multi-functional fiber that can harvest energy and detect strain, which can be applied to future wearable electronics.

Imagine a world where smartphones, laptops, wearables, and other electronics are powered without batteries. Researchers from MIT and elsewhere have taken a step in that direction, with the first fully flexible device that can convert energy from Wi-Fi signals into electricity that could power electronics.

The heart's motion is so powerful that it can recharge devices that save our lives, according to new research. Using a dime-sized invention the kinetic energy of the heart can be converted into electricity to power a wide-range of implantable devices.

Researchers have created a new concept of thermoelectric material, a device composed of cellulose, produced in situ in the laboratory by bacteria, with small amounts of a conductive nanomaterial, carbon nanotubes, using a sustainable and environmentally friendly strategy.

The piezoelectric materials that inhabit everything from our cell phones to musical greeting cards may be getting an upgrade. Researchers have developed methods to 3D print piezoelectric materials that can be custom-designed to convert movement, impact and stress from any directions to electrical energy.

Healthcare electronics is rapidly deploying for wellness, electroceuticals, intrusive medical procedures and more, powered by new technologies.

Clothing embedded with tiny solar cells the size of a flea will allow wearers to generate electricity on the move and charge items like mobile phones and smartwatches.

A new mechanism for ultra-efficient charge and energy flow in graphene, opening up opportunities for developing new types of light-harvesting devices.

Battery-free eye-tracking glasses could create an even more realistic experience for augmented reality enthusiasts. The new technology improves player controls for gaming and allows for more accurate image displays.

The key next iteration for fiber reinforced polymer products will be the concept of multifunctionality. This is the idea of making a structural part carry out additional role(s) beyond their current primary mechanical task - the market for smart composite material is forecast to exceed 5 kilotons by 2029.
