Oluwatobi “Tobi” Oyinlola, a Nigerian-born researcher at the Massachusetts Institute of Technology (MIT), has been recognised by Guinness World Records for creating the world’s smallest GPS tracking device.
The device, a prototype measuring just 22.93 mm by 11.92 mm, is smaller than a thumbprint. Designed in Cambridge, Massachusetts, it carries a printed circuit board, an embedded antenna, and supports GPS signal reception, data logging, and Bluetooth streaming. The creation was reviewed and verified by two engineers and an architect, ensuring it meets the technical criteria for the record.
Tobi’s idea was born from a practical challenge. Most available GPS units were not suitable for the compact systems he had in mind. “I realised that if we wanted to embed GPS functionality into cutting-edge wearables, medical devices, or tiny sensors, we needed to dramatically shrink the technology,” he said.
Driven by that problem, he developed a device that fits into small systems without reducing performance. The prototype can be embedded in items such as wildlife tags, personal safety tools, and healthcare equipment. “My goal was to develop a tracker so compact that it could be embedded in almost any object or device without compromising functionality,” he explained.
The record-breaking device marks an important step in the evolution of location-based technology. It also highlights innovation by Africans in global research spaces.
The achievement has sparked reactions from leaders and innovators. President Bola Ahmed Tinubu congratulated Tobi, stating, “You have just shown the world that Nigerian youth can.” The Minister of Communications, Innovation and Digital Economy, Dr Bosun Tijani, said, “As we empower more young innovators to break barriers and lead in cutting-edge technologies, we secure Nigeria’s rightful place on the global innovation map.”
Tobi’s journey began in Nigeria, where his interest in technology started at age 13. His school’s computer lab, donated by alumnus Seyi Makinde—now the Governor of Oyo State—introduced him to computing. That early exposure led to a path from secondary school in Nigeria to MIT and now to the Guinness World Records.
“Honestly, it feels incredible and a bit surreal,” Tobi said. “I’m extremely proud of the achievement and deeply honoured to have my work recognised.”
