Tracking firefighters in burning buildings

Science Daily  March 1, 2019
An international team of researchers (Canada, USA – UCLA, Czech Republic, Sweden) has developed a fire-retardant and self-extinguishing triboelectric nanogenerator (FRTENG), which can be utilized as a motion sensor and/or power generator in occupations such as oil drilling, firefighting or working in extreme temperature environments with flammable and combustible materials. The device takes advantage of the excellent thermal properties of carbon derived from resorcinol-formaldehyde aerogel. The FRTENG is not flammable, shows exceptional charge transfer characteristics, leading to a potential difference up to 80 V and a current density up to 25 µA/m2. When integrated into firefighter’s shoes, the FRTENG can discern the movements of a firefighter in hazardous situations…read more. TECHNICAL ARTICLE
