Timeline: Smartphone-enabled health devices

By Aditi Pai

By Aditi Pai, Jonah Comstock, & Brian Dolan

Colbert TopolMobile health has come a long way since the start of 2009 when Apple demonstrated on-stage at its World Wide Developer Conference how blood pressure monitors and blood glucose meters could connect to the iPhone 3G via cables or Bluetooth. MobiHealthNews has tracked health-related wearable devices from their infancy as research projects at university labs to the commercially available products they are today. The past three Consumer Electronics Shows, especially, have yielded a wide range of smartphone-enabled health and fitness devices, from smart forks to connected pulse oximeters and, of course, the numerous wearable activity trackers.

While it's not yet fair to say that every wearable health-related device connects to smartphones, almost all of them have companion smartphone apps that display data collected by the device. The smartphone is the hub device for today's wearable devices.

As we're almost halfway through 2013, it seemed like a good time to stop and take a look back at the rise of smartphone-enabled health and fitness devices over the course of the past five years. Below is a comprehensive, but admittedly not exhaustive, timeline of important events and news announcements related to smartphone-enabled health and fitness devices.

BradMarch 19, 2013: Three subcommittees in the US House of Representatives Committee on Energy and Commerce devoted three days of hearings to the FDA's regulation of mobile medical apps and smartphone-enabled medical devices. One of the contentions raised ahead of the hearings, which was one reason the hearings were held in the first place, was that the FDA might begin regulating consumers' smartphones as medical devices since they had medical apps on them. Some legislatures told talking heads on the cable news networks that this would result in the price of the iPhone going up because designating mobile phones as medical devices carried a new tax under the health reform legislation. Apart from a number of humorous conversations between digital health industry folks and members of congress over regulatory minutia, like when a wireless-enabled weight scale become a medical device, not much was accomplished during the hearings. It did, however, drum up interest in mobile health. Read More
