"Wellness" computers that monitor your pulse, temperature and other health indicators are becoming increasingly sophisticated and varied to cover every aspect — and age — of human life. Some products, like the ring by Finnish startup Ouraring, are specialized in optimizing physical training by tracking sleep patterns and physical activity. Health gadgets took the limelight at this week's Slush fair, a gathering of technology startups that has drawn 800 investors and an estimated 15,000 participants worldwide. Lasse Leppakorpi, the founder and CEO of Beddit, a startup specializing in sleep-monitoring equipment, says new gadgets will increasingly change the role of doctors to becoming "consultants and experts" for people concerned about their well-being. Earlier this year, the Technical Research Center of Finland launched a digital maternity package complete with pacifiers that can monitor babies' sleep, well-being and physical development. Ouraring's ceramic finger monitor registers activity during physical exercise, helping users plan training and recovery by linking the digital data to a cellphone app.
