Joint technology collaboration

The application of sensors to measure anomalous vibrations in various media is one of the current technological trends. The reason is directly related to the prevention of accidents in structures in general. From bridges to airplanes, through pipelines or industrial machinery, to fault detection, it can identify small problems that reduce equipment productivity and help prevent serious accidents. It is no wonder that the Research Institutes of Sweden (RISE) recently opened a business area focused on distributed fiber optic sensors, which counts with Carolina Franciscangelis on its Brazilian team.

The researcher explains that the use of optical fiber has been gaining space mainly because it is much easier to be embedded in the most different structures without causing damage. Another factor that comes to the attention of the market is the material’s high resistance even when applied in noxious environments, such as those involving high temperature or corrosive products, for example. The excitement is so great that Saab AB itself is contributing in these surveys by envisioning the possibility of installing the sensors in their aircraft.

The arrival of Carolina to RISE occurred through a CNPq-CISB-Saab call, in 2015, that allowed her to carry out part of her sandwich doctorate in the Swedish institution, which began at the State University of Campinas (Unicamp). At the time, she was also working at the Research and Development Center (CPqD), an entity that has been working in telecommunications since 1976, but has been incorporating new business into its portfolio since its privatization in 1998, such as bank and electrical software, among others.

“Carolina is a very good researcher. She had an excellent performance in the master's degree program", praises João Batista Rosolem, from CPqD’s Device and Sensor Development Management. For him, the engineer's departure strengthened the bond with RISE.

"The focus of my master's degree was in optical monitoring while in CPqD I was working in the broadcast area. This allowed for knowledge in two areas that complement each other, since many devices have a background in telecommunications,” he explains. After completing her doctorate in 2017, Carolina returned to RISE the following year, this time as a hired employee. "We made RISE's first distributed sensor," he says.

Rosolem projects the maintenance of the strong bond between the two institutions, including with the addition of new chapters in the next years. Among the expected projects is the opening of possible visits between researchers of the two institutions and the publication of joint articles.
