Long-lasting insecticidal bednets, or LLINs for short, are an integral part of the global effort to fight malaria, with the WHO recommending that everyone, all 3.4 billion people, at risk of malaria should have access to one.

But how effective are they? To try and understand how bednets are being used in the field, a team of researchers led by Paul Krezanoski of the University of California have developed the so-called SmartNet, a remote bednet monitor.

I speak to Paul about the unreliable mechanisms of monitoring bednet use and the technology behind the SmartNet.
