MassChallenge marked the end of its first digital health cohort PULSE@MassChallenge with assurances from Massachusetts Gov. Charlie Baker that the Commonwealth would back a second class of digital health businesses and provide funding for health technology innovation center TechSpring. Health technology businesses with eye tracking technology for concussion detection, virtual reality to reduce social isolation for nursing home residents and a telehealth alternative to ambulance radios were among the 31 participants in the inaugural class to be singled out at the Boston event.
