The Cosinuss Bluetooth headset is a bit different from conventional Bluetooth headsets. It’s different because it can also record your heart beat, with the help of your ears. That’s because it contains a sensor that can detect the rush of blood under the skin of your ear. Ever wonder why your ears turn red when you blush? Well this works on much of the same principle.
The Cosinuss sports tracker is special because conventional methods to record heart beat have been error-prone. Chest bands, a popular way of measuring the heart beat, often rely on proper levels of perspiration to be effective. The Cosinuss works simply because you just have to put it onto your ear and viola! It’ll start taking readings. The device was shown in Hanover at the Cebit trade show as part of the Code_n startup competition. The device is still under development but to enter the competition they had to incorporate at least one sensor. Additional sensors for measuring core body temperature and blood oxygen saturation levels will be included in the final device as well. Despite looking like a regular Bluetooth headset, the Cosinuss sports tracker packs a surprising amount of hardware. It has an on-board battery and a micro-USB charging socket, along with all the sensor hardware.
The Cosinuss sports tracker can transmit the data it collects to a smart device via two supported standards. There’s the usual Bluetooth LE standard. In addition to that, Cosinuss also supports the ANT+ interface. ANT+ is an ultra low-power wireless protocol that is supported by many modern fitness devices and the Samsung Galaxy S4/S5 smartphones. The Cosinuss sports tracker will be available in the fourth quarter of this year, with a retail price of around $208. Team Cosinuss haven’t built a dedicated app for the sports tracker yet, leaving it up to third-party developers for the moment.
