Temporary tattoo to measure blood glucose
The new procedure might replace finger pricks
The day that diabetics could do away with painful finger pricks to measure blood glucose may not be too far away. Researchers from the University of California in San Diego have developed a non-invasive, cost-effective and virtually painless method of measuring blood glucose levels – in the form of a temporary paper-based tattoo.
These tattoos work by applying a mild electrical current, drawing glucose to the surface of the skin where it is measured. The concept is not new; the tattoo’s precursor is the GlucoWatch wristband, which also used electrical shocks to capture readings. Unfortunately, it was discontinued after reports of discomfort, IFL Science reported.
In a study consisting of seven participants with no history of diabetes, each person consumed a carbohydrate-rich meal while wearing the tattoos. The devices picked up spikes in blood glucose just as effectively as the traditional finger prick method.
Most notably, while some participants felt a minor, short-lived tingling sensation, none of them reported any significant discomfort, reported Science Magazine.
While this new technology is at a very preliminary, proof-of-concept stage of development, the researchers are hoping to create a version that will be able to send numerical readings through Bluetooth to the patient’s doctor. In fact, future possibilities are wide-ranging – the technology could be adapted to deliver medicines, for example, IFL Science reported.
