Although we don’t want to admit it, there will come a time when we will get old and things will begin to “break” in our body. To be sure that doesn’t happen too often there is always the possibility to know vital information about what happens and where.
Tensio is an electronic blood pressure reading bracelet designed to keep tabs on your vital signs without appearing to be an medic-alert device. The core is cushioned with inflatable foam to take the reading and results appear on a display or through a tactile, braille surface. In case of emergencies, Tensio can wirelessly call for help.
It's made from a soft rubber at the exterior ,and the inside is made of foam that inflates when you turn the device on and place it on your wrist.

This is a concept.
