Health-monitoring bracelets are such a thing of the past. Researchers have now one-upped companies like FitBit by developing a wearable skin patch that can send data wirelessly to smart phones and PCs.

Created by researchers at the University of Illinois at Urbana-Champaign and Northwestern University, the patch is designed to keep tabs on the user's health at all times. Among its uses are tracking muscular activities and monitoring illness-related symptoms.

The soft and flexible patch adheres to the skin and uses a microchip to pick up the subtlest of body movements, including abnormal movements like tremors. The team of researchers was able to fit the microchips into the patch through the use of microfluidics and "origami interconnects."
