Benedetto Vigna (born 1969) is an Italian physicist and technology executive notable for his contributions to micro‑electromechanical systems (MEMS) and for leading the development of motion‑sensing technology employed in modern mobile devices. He served as chief technology officer (CTO) of STMicroelectronics, a major global semiconductor manufacturer, where his work on MEMS inertial sensors enabled the widespread inclusion of accelerometers and gyroscopes in smartphones, tablets, and other consumer electronics.
Early life and education
Vigna was born in Italy in 1969. He earned a Laurea (equivalent to a Master’s degree) in physics from the University of Bologna in 1993. He subsequently obtained a Ph.D. in physical sciences from the University of Pisa in 1998, focusing on micro‑fabrication techniques and sensor technologies.
Career
STMicroelectronics
- 1994–2005: Vigna joined STMicroelectronics’ research laboratories shortly after completing his undergraduate studies. He led projects on the design and fabrication of MEMS devices, concentrating on miniaturized inertial sensors.
- 1995: Along with colleagues, Vigna co‑invented a three‑dimensional MEMS accelerometer that could detect orientation and motion with unprecedented accuracy while consuming minimal power. The device became a core component of the first generation of motion‑sensing smartphones, including the Apple iPhone introduced in 2007.
- 2005–2022: Vigna was appointed CTO of STMicroelectronics. In this role he oversaw the company’s technology strategy, research and development programs, and the integration of MEMS and sensor technologies across ST’s product portfolio. Under his leadership, ST expanded its MEMS sensor business into new markets such as automotive safety, industrial instrumentation, and wearable health devices.
Other activities
Since leaving his CTO position in 2022, Vigna has remained active in the technology sector as an advisor and board member for several startups focused on advanced sensor applications and materials science. He has also contributed to academic and industry conferences on MEMS, nanotechnology, and semiconductor innovation.
Recognition and awards
- MIT Technology Review TR35 (2005): Listed among the top 35 innovators under the age of 35 for his work on MEMS inertial sensors.
- IEEE Sensors Council Technical Achievement Award (2013): Recognized for pioneering contributions to the development and commercialization of MEMS motion sensors.
- Edison Award for Innovation (2015): Honored for the impact of MEMS technology on consumer electronics.
