When robots take over... your fascination for technology: an interview with Julien Ghaye

When Julien Ghaye mentions at parties that he does “something with robots,” it often sparks wild imaginations. While many people picture robots as machines with moving arms and talking gadgets, the reality is that robotics technology goes far beyond these stereotypes. In this interview, Julien reveals the broader impact and possibilities of robotics nowadays.

How did you get into robotics?

Julien shares, “I joined Melexis in 2018 as a Mixed Signal Design Engineer, where I focused on verifying and optimizing integrated circuit (IC) designs, primarily for the automotive sector. With the growing prominence of robotics”

What attracts you to robotics?

“I’ve always been fascinated by the futuristic aspects of technology, especially the potential of robotics. As a child, I was engrossed in science fiction and manga, dreaming of a world where robots and humans coexisted. That fascination fueled my love for creating and understanding how things work. I still enjoy ‘fixing stuff’ and remain endlessly curious about how systems work. Give me a screwdriver, and I can entertain myself for hours,” he smiles.

What does Melexis do in terms of robotics?

Julien explains: “At our Innovation Lab in Bevaix, we focus on developing advanced sensing solutions that empower robots to interact with the world. Our core technology is based on the Hall effect, which we implement in various forms. A prime example is Tactaxis, a soft sensor that gives robots a sense of touch. This 6 x 6 x 5 mm3 sensor uses magnetic fields to measure the 3D force applied to its surface accurately. What sets it apart is its high sensitivity combined with resistance to stray magnetic fields.”

For what purposes can Tactaxis be used?

Julien: “Tactaxis can be integrated into robotic grippers for tasks like picking fruit or vegetables, ensuring precision and care. It’s also valuable in healthcare applications, such as an arm prosthesis where Tactaxis has the potential of giving back tactile feedback to the wearer. It’s a technology that truly has the potential to enhance people’s lives.”

What do you see as the biggest challenge to advancing robotics?

Julien: “The biggest challenge is enabling robots to work seamlessly alongside humans, which requires interdisciplinary collaboration. A great example of this approach is BruBotics, the Brussels Human Robotics Research Center at the Vrije Universiteit Brussel (VUB), where experts from various fields collaborate on robotics solutions for healthcare. In one of these projects, Melexis contributed as a research partner by providing Tactaxis sensors embedded in an arm cuff. These sensors detect the user’s intention to move, allowing the robot to provide gentle assistance and help the user perform movements.”

Are you worried that the influence of robots might be taking a wrong turn?

Julien: “If I were scared of that, I wouldn’t be working in the Innovation Lab! I understand the concerns about robots potentially displacing jobs or causing harm. But I trust that the right, smart people are involved in robotics, prioritizing ethical considerations. There are countless opportunities to use robotics for positive impact, from healthcare to daily tasks. Instead of fearing robots, we should focus on how they can be harnessed to improve lives.”

What did you learn from your experiences in the Innovation Lab?

“A key lesson I've learned is that innovation thrives on open communication and collaboration. Ideas often need to be nurtured and refined through dialogue and diverse perspectives. We shouldn’t hesitate to share our thoughts, even if they're not fully formed. By embracing feedback and working together, we can transform initial concepts into groundbreaking innovations. That's the power of teamwork," Julien concludes.

What would you say to people who think, "This looks like a fun field to work in"?

Julien: “Take advantage of the opportunities to learn and gain experience. Don’t hesitate to reach out to companies for internships or interviews. People are often more than willing to help. Recently, I received a request from a student seeking information and experiences to share. I admired that initiative because, at that age, I might have been too shy to ask. So, don’t be afraid, and don’t let anything hold you back.”
