Wireless sensor networks and chemo-/biosensing

The domain of wireless sensor networks (WSNs) also have uses in the field of chemo-/biosensing and communications technologies. They can be used in the development of wearable sensors and applications in personal health monitoring as well as the more challenging field of control of surface binding and fluid movement. Studies in such fields concentrate on so-called motes rather than mobile phone technologies. Nevertheless, challenges do exist such as the issue of delivering sensing platforms that are appropriate for integration into scaled-up deployments in terms of sustainability, cost and reliability issues. Despite promising routes to intermediate scale up in the short-to-medium term by microfluidics, they still require regents and generate waste. As such, studies on the real deployment of chemo-/biosensor networks are few and far between and are only starting to be realized.
