About Gentag


Gentag is a visionary IP and technology development company that combines its advanced knowledge in biology, chemistry and microelectronics to convert consumer safety and health concerns into everyday disposable sensors that will revolutionize diagnostics, proactive medicine, nutrition and the everyday lives of consumers worldwide.

Gentag, Inc. and its patent holding company, Altivera, LLC, hold 66 issued patents covering cell phone-based consumer safety sensors, IoT sensors and sensors for instant diagnostic tests. These combined technologies allow for a range of groundbreaking consumer applications, from simple IoT sensor readings such as temperature or packaging tamper resistance, to sophisticated consumer health applications including biomarker analyses and COVID-19 detection.

In addition to its NFC sensor portfolio, Gentag is also developing an optical blockchain sensor platform for new types of consumer market sensing applications. Optical blockchain sensors have broad market applications, including for food safety, bacterial detection, consumer health and mobile payments. They can be mass produced rapidly and at a very low cost.

John Peeters, Ph.D., Founder and CEO

Dr. John Peeters started laying the IP foundation for Gentag in 2001. An expert on biomarkers, sensors, and nanotechnologies, he holds numerous issued U.S. and international patents. John obtained a doctorate in applied biology from Cambridge University in the UK. He also holds a master’s degree in genetics and a bachelor’s honors degree in biology. Dr. Peeters predicted and patented a number of key technologies well before their time, including DNA sequencing in a nanotube (US patent 6,123,819), NFC cell phones sensor networks (US patent 7,148,803), and the closed loop cell phone diabetes insulin delivery system (US 8,077,042).
