Wearable health sensors, better known simply as wearables, combine advanced computer technology with our bodies. Companies like Google, Apple, FitBit, and ore are focusing on health monitoring. Most commonly, these wearables are used as fitness trackers that record our footsteps, heart rate, sleep, and calories burned.
As strides are made in microtechnology and micromachining, these health sensors will evolve into more complex devices, yet become even smaller. The thought of wearing a bulky bracelet to monitor heart rates will be replaced with adhesive sensors similar to a sticker. These sensors can be worn directly on the skin and the material used makes them bendable and stretchable. So, how does microfabrication play a role in this emerging field of wearables? Let’s find out!
