South Korea: Researchers at Incheon National University have discovered an optimal conductive carbon fibre volume for cement-based conductive composites for use in net-zero energy buildings. The team reported that a 1% conductive carbon fibre content facilitates maximum energy generation from the movements of occupants and the weather against floors and walls. It also enables the storage of electricity at safe voltages. The product is based on triboelectric nanogenerator (TENG) technology.
The team published its results in the journal Nano Energy in November 2021.
