It includes a GSR sensor to distinguish whether the wearable is being worn. Galvanic skin response sensors, whether it's working alone or alongside other sensors, can tell us a little or whole a lot. That's why makes sense that companies making wrist-worn wearables are playing around with GSR sensors on that particular part of the body. Those sweat glands can be found all over the body, but there's a whole lot of them situated around the hands and the feet. That's why it's considered a good fit for both fitness trackers and stress combating wearables for instance. Sweat glands are tied to our nervous system and body processes like our immune system, so GSR can help tap into information about our current physiological and psychological state. When you sweat more, the electrical conductance in the skin changes. This electrical conductivity is tied to changes in moisture levels in the skin when the sweat glands are more active. Essentially, GSR sensors are able to measure the electrical conductivity of the skin using electrodes. Understanding exactly what happens when the sensors are called into action. Used along with sensors to measure pulse rate and blood pressure, it's helped sniff out the telltale physiological indicators of fibbing to the police. The ability to measure galvanic skin changes, also known as electrodermal activity, goes way back to the 1800s, but in modern day terms it's probably best known for being the tech you find inside a 'lie detector' test.Īs we covered in our origins of the fitness tracker, it's was cropping up in lie detector machines to carry out polygraph tests before World War II. So why is GSR a big deal? We explore how it works and what it's going to bring to the wearable tech party.īefore we get on to what a galvanic skin response sensor actually does, we're going take a look back at how it came to prominence and why you might actually be more familiar with it than you think. It's also set to feature inside Vinaya's upcoming Zenta biometric bracelet and the emotion sensing Feel wristband.
Galvanic skin response sensors have appeared in both versions of the Microsoft Band, the Jawbone UP3 and the recently recalled Intel Basis Peak. Read this: What wearables will measure in the future We're starting things off by taking a closer look at a sensor that's starting to creep its way into more devices. That's why we wanted to start honing in on the sensors and features that make our wearables tick. It's also not always clear exactly what that new tech does or how it's going to help you measure, track and analyse. It can be a bit of a minefield keeping track of all of the tech being crammed into fitness trackers, smartwatches and VR headsets, though. Wearables are getting smarter and that's a good thing.
