Nest’s motion sensing tech could make it into assisted-living facilities for seniors. Nest is quietly planning a move into digital healthcare off the back of its purchase of Seattle-based startup Senosis Health. Google’s smart home brand has remained tight-lipped since the deal came to light in August 2017. But its secret is revealed in internal communications and financial documents on the Senosis acquisition obtained by GeekWire.The filings show that it was in fact Nest, not Google, that snagged the company; a UW spinout that turns smartphones into health-tracking tools using their built-in sensors. Its products include HemaApp, which checks your blood’s hemoglobin count using your phone’s camera, while SpiroSmart uses the microphone to measure your lung functions.Only Nest isn’t ready to go public with the move just yet. Records show the firm has been ordering personnel not to mention the company’s name and barring UW from publicizing the deal. “It turns out Nest is much more secretive than the rest of Google or Alphabet,” Senosis co-founder Shwetak Patel wrote in a June 2017 email to UW’s Fiona Wills. “They seem to be particularly sensitive in this situation since they don’t want people to know they are getting into a whole new line of business, digital health, until they are ready to publicly announce.”
