Owlet Baby Care, a tech startup developing smart socks for monitoring infants’ vital signs, raised $6 million in venture funding and another $1 million in the form of an NIH Grant.

Along with the funding announcement, the company planned to finally make its smart sock device available to the public this fall. Some users do already have the device, since it was crowdfunded in a 2013 campaign that raised $227,000 and those early backers had a first shot at owning the device. The plan is to retail the device for $250.

The “smart sock” is intended to be worn by a sleeping baby, and it tracks heart rate, skin temperature, blood oxygenation, and sleep data. That’s all transmitted to the cloud and accessible through an app on the parent’s phone or via any internet-connected device through a web portal.

The Owlet is not yet FDA-cleared.
