Designed to help firefighters communicate independently of unreliable traditional systems such as cellphone networks, i-Garment's "smart suit" does more than just enable voices to be heard. The suit also packs in location and health monitoring, with a whole infrastructure behind it including multiple stages from the field vehicle back to HQ. The European Space Agency recently approved the suit after a series of tests including firefighting scenarios: it's not currently planned for the US, but it wouldn't be surprising to see this or a similar system over here sometime soon.
