Despite lower than expected sales, wearables continue to be a growing market segment. Consumers spent over $2 billion on wearables in 2015 and are increasingly demanding better performance. One emerging application area for wearables, accurate biometric sensing, is highly complex and requires sophisticated solutions to provide accurate measurements during regular use, as well as during high-intensity workouts. The best performing solutions on the market are designed using a systems approach where both hardware and software are tightly integrated. Valencell is one of the developers of biometric sensing module technology for wearable devices. The company has raised a total of $24.5 million in venture funding to date, including $11 million in March of last year. We spoke with Ryan Kraudel, VP of Marketing at Valencell, to get the latest trends for biometric sensing in wearables including emerging applications and competitive dynamics.
