The torrent of evidence for new products with a focus on health and fitness is astonishing, including a wide range of top experts Apple has hired. According to AppleInsider, a report last week in China's Electrical Engineering Times said that Apple is considering using optoelectronics in their rumored iWatch to monitor pulse and blood oxygen levels. This technology measures the changes in light reflected by the body. Light from small LEDs is projected onto one's finger, for example, and then the sensors measure the amount and color of the light reflected. From this it can determine how fast your heart is beating and how much oxygen saturation there is in your blood. Adding to the credibility of this report is the fact that Apple has hired experts in this area in recent weeks. Whether this technology is slated for an iWatch or other wearable device is unclear, but it appears likely that Apple is developing a product that will use it.
