Monitor Heart Health Using Paper-Thin Electronic Skin

Stanford engineers have succeeded in combining multiple layers of flexible materials to create a new type of pressure sensor. The final sensor is thinner than your currency note and the team believes that one day, it would be possible for them to completely monitor patient's heart conditions in real time. Zhenan Bao, professor o Chemical Engineering at Stanford led the team to create this innovative electronic skin that can be worn on the wrist and can help track stiff arteries and cardiovascular problems.


Engineers created a thin rubber layer at the middle mounted with tiny pyramid-like bumps, each being a few microns wide. When pressure is applied, these pyramids deform slightly causing change in the size of the gap between two halves of the device. This change in the space causes measurable changes in the electronic field & current flowing through the circuit. This sensor can measure the pulses when put up on the wrist using an adhesive bandage.

The team is currently working making the device completely wireless. It would allow the doctors to monitor patient's heart conditions almost in real time from anywhere in the world.
