Despite the advances in sweat-monitoring biosensors the technology has had one major hurdle to overcome: the patient needs to sweat to make it work. Now a team has developed a sweat-stimulating biosensor that activates perspiration while the subject relaxes.

We've already seen a few portable electrocardiographs that let users monitor the electrical activity of their heart, wherever they may be. Researchers from Spain have just developed a system of their own, however, which offers something that most others don't.

In order to monitor their blood glucose levels, diabetics typically have to perform finger-prick blood tests. Scientists from the University of Texas at Dallas, however, are creating an electrochemical biosensor that continuously measures glucose in the wearer's sweat.

Health and fitness monitors may have come along in leaps and bounds, but there's still a whole lot they don't know about us. Placing miniaturized sensors deep inside our bodies would be one way to change that, and now it seems such a technology mightn't be so far away.

As part of its move towards mobility, Ford has run an experiment in which it monitored how well people were driving and provided them with a score. This could then be used to provide insights via an app into how driving could be improved, as well as possibly leading to good drivers saving money.

It's not quite the tricorder from Star Trek, but researchers responsible for a new wearable patch that can monitor the body's biochemical and electrical signals at the same time say their first-of-its-kind device could be a step in that direction.

Chevrolet has created the OnStar Proactive Alert system, which senses if something isn't quite right under the hood and prompts drivers to get their vehicle serviced before more expensive or ill-timed breakdowns occur.

The BACtrack Skyn sensor can be worn on the wrist and pairs with a smartphone app to offer real-time monitoring of alcohol levels, even pinging the user's phone when they drinking too hard.
