These sensors are as fine as spider's silk and can monitor human health
Bioengineers have successfully developed sensors as fine as spider's silk. Researchers at the University of Cambridge in the UK say the extremely light sensors could be used to monitor human health, such as heartbeats, or to detect detailed changes in the environment. The sensors are 50 times thinner than human hair and so lightweight that the scientists were able to print the fibre directly onto a dandelion without it collapsing. In a recently published study, the sensor was tested to pick up signals such as heartbeats in the same way as an electrocardiogram (ECG). The research team says the ...
