Wearable electronics was once a pipedream. Not anymore, as we see more and more wearable devices appear, and one of the key growth application areas is wearable health. To unleash the full potential of wearable health, solutions must become truly personalized, and devices must deliver high quality data. They need to become thinner, more flexible and stretchable so they are more comfortable to wear. Power consumption needs to be reduced to improve autonomy. And we need to expand the range of wearable functionality available to open up new healthcare, as well as consumer lifestyle, applications.
