Think that your headphones should do more than just deliver music to your ears? Well, the Pulsar headphones are a result of collaboration between the European Space Agency and the Swiss tech company CSEM. Using existing ESA technology, the earphones send an inrared signal through your ear tissue/cartilage, reading your heart rate and sends it back to the device. The prototype currently works with an iPhone and features a special passthrough adapter plugged into the headphone jack and a custom app for visualizing data. This technology could also be improved to provide more detailed information such as oxygen levels in the body.
