Weak Signal's description 
Everyone is talking about biotechnologies nowadays, which is a good indication that there is potential there. People cannot imagine what can be done really. If you talk to people who work in this area, it is clearly very new and very immature, but looking at current research we can come up with the ideas that body sensors might be possible in the future. Or some body computers, like those in cars, which indicate when fuel will be required. With the body we only go to the doctors once we have a complaint. If we could get weak signals of something coming, we could help ourselves and reduce the load on the health system.
