Start-up develops vitamin measurement pen A start-up has developed a non-invasive device which allows users to check 30 most important vitamins and minerals and has secured substantial financial backing on the Indiegogo crowd-funding website. The pen-like device is called Vitastiq and uses a smartphone as an interface. The device uses a method called electro-acupuncture (EAV), a traditional technique for measuring vitamin and mineral levels. EAV is a form of acupuncture where a small electric current is passed between pairs of electrodes. Resistance of the body tissue is used to measure vitamin and mineral levels in comparison with a reference point. An electrotrode in the pen tip creates an electrical circuit with the body through a second electrode in the pen case. The smartphone app saves and evaluates previous reading from the device. The Croatia-based company has been working on the device and iOS app development for two years. Following the funding they company is now preparing for volume production and a commercial launch of the product next month. An Android app will be introduced in April.
