Wearable sensors are becoming more and more popular although still mainly in the sports and fitness environment. The sensor e.g. a pedometer, provides continuous measurements and stores the data on a smart device, usually a phone or watch. Customers nowadays want to know more, record more and analyse more, the market for really smart sensors is increasing. Sensor development for perspiration analysis is well on it’s way, the EmStat Pico is the perfect candidate to accelerate that development. The size and low power consumption make it the perfect platform for a wearable smart detection device.
