Rice University researchers used conductive carbon nanotubes to develop shirts that can monitor heart activity

This thread is sewn into a seemingly ordinary ready-made sweatshirt, which can monitor the heart rate and perform continuous echocardiographic examination of the wearer . The carbon nanotube fibers used in shirts are as conductive as traditional metal wires and can be washed with water or even machine. In addition, carbon nanotube fibers are more flexible than metal wires and are not easily broken during body exercise.

Another major benefit of the smart shirt is that it is better at collecting data than standard chest strap monitors when performing field measurements in experiments. The shirt is also compatible with medical monitors on the market and provides more accurate ECG results.

The researchers pointed out that in order to obtain accurate readings, the shirt must be designed to fit snugly against the chest. The team plans to continue to develop their smart shirts, and in future research, more carbon nanotubes will be used to increase the contact area with the skin.

The newly developed carbon nanotubes are also easy to integrate into fabrics using traditional sewing methods. The conductive thread is sewn into the fabric of the shirt in a zigzag pattern so that it can be stretched without breaking. The line can also be connected to an electronic device, such as a Bluetooth transmitter, and then wirelessly send data to a smart phone.
