Smart coal mine helmet uses Li-Fi sensor alerts
—
in EngineeringWhat the study found The authors present a smart safety helmet for coal miners that uses Li-Fi, or light fidelity, to transmit sensor data. The helmet is designed to monitor heartbeat, humidity, gas, and temperature and to send alert messages to mobile phones and email for authorized people. Why the authors say this matters The…
EO comb system combines high-capacity transmission and sensitive sensing
—
Integrated sensing and communication system using electro-optic comb and 7-core fiber achieves 10.56 Tbit/s transmission with acoustic sensing, eliminating crosstalk through polarization multiplexing.
