After several years of testing and development, a miniature device is now available* that can monitor a range of substances in the blood, providing instant results via mobile phone. Inserted by needle and placed just beneath the skin, it can remain in the body for months before needing to be replaced or removed.
This tiny laboratory measures 14mm (0.55") and comprises five sensors, a coil for wireless power as well as miniaturised electronics for radio communication. The entire system is powered by a mere one-tenth of a watt. Each sensor's surface is covered with an enzyme that is used to detect chemicals like ATP, glucose and lactate. Data is transmitted via Bluetooth to a mobile phone, which can then be sent to a doctor, if necessary.
