Microneedles and suction cup for blood diagnostics, modeled on leeches

A new device for taking blood samples uses microneedles and a suction cup instead of a large needle. People with a phobia of needles stand to benefit. More blood can be obtained than with the classic finger prick, making diagnostic measurements more reliable. Because the device can be produced at low cost, it is also suitable for developing countries.
