Technological progress never ceases to amaze us and thanks to this, the wide world of medicine updates its methods and forms that guarantee the well-being and health of human beings.
Now, a novel health monitor with a smart bracelet, just like an ordinary wristwatch, is capable of tracking heart rate without the need for batteries or any kind of power source. The ingenious invention also guarantees that communication can be generated wirelessly through electronic devices such as a tablet or a mobile cell phone.
Data collection
Constructed through 3D printing after being applied with nanomaterials on flexible substrates, the monitor is helpful in collecting self-powered radial artery pulse data, however, it also serves to monitor body temperature and blood pressure.
Nanogenerators are electrical materials, which convert the user’s movement into electricity, which explains why the device does not need a battery. Integrated near-field communication technology facilitates wireless power and data exchange between the wristband and mobile device, and biophysical information is plotted and presented via an app on the screen.
Rahim Esfandyar-Pour, a professor at the University of California, Irvine, said: “This self-powered wireless device allows you to do this without relying on a battery, which can lose its charge and has the problem of thermal runaway (battery overheating). of lithium ions that can lead to combustion)”.
These nanogenerators are created using titanium-based MXenes (a class of two-dimensional inorganic compounds), a virtually new type of ultrathin 2D material with electrical and mechanical qualities. MXene layers are just a few atoms thick, flexible, stretchable, and can be printed on the surface of flexible material much like a bandage or wearable arm or bracelet.
