Fiber-optic cables can be used to detect rumbles of thunder: Study

Vibrations from loud events like lightning pass from the air to the Earth’s surface. Underground fiber optic telecommunications, which carry internet and phone service, can pick up the rumble of thunder underground, an advance that can offer scientists a new way to detect environmental hazards, and image deep inside the Earth. The study, published in …

Light transmitted through wood-based optical fibre

Light has travelled through a wood-based optical fibre, offering the possibility of biodegradable Internet of Things (IoT) sensors or simple moisture monitors. Researchers at VTT made the new fibre, which has a core of wood cellulose modified with ionic solvents developed at the Finnish research centre. The core has a cladding of cellulose acetate. Light …
