Dutch researchers have demonstrated a new type of network – not LAN or WAN, but BAN, the Body Area Network. What this means is that sensors in your body (for example electrocardiogram sensors monitoring your heart, or EEGs monitoring your brain) can now communicate via radiowaves to a wearable computer hung round the neck. This computer can send you a text message if readings stray from the norm. Your body will text you when it needs medical attention!

Making a smarter bandage

Despite advances in modern technology, bandages haven’t changed much since the days of poultices: Apply an ointment, wrap up the injury, and change it after a while. That may change, however. As we learn more about how the body heals, how bacteria develop resistances, and how to do things on a very small scale, we’re rethinking the way we dress and treat wounds.

Consider, for example, researchers in the UK who’ve designed smart dressings that can heal wounds without making bacteria resistant. In a more low-tech example, MIT students have found a way to use suction to heal wounds faster, using only airtight wrapping and a squeeze bottle to apply negative pressure. The system is currently being tested in Haiti.
