The last robot I had to build had to mimic a human oesophagus (food tube) and the swallowing motion called peristalsis. The human oesophagus works by squeezing the food to the stomach, kind of like squeezing toothpaste from a tube of toothpaste. This was a very difficult motion to replicate and to make the materials move in the way a human oesophagus does. But it was lots of fun and worked out great!
Recently I 3D printed a metal stent (a device used to open vessels that are struggling to let blood flow through them) that is quite flexible. Usually, 3D parts are quite stiff so I was very proud when we managed to make a new flexible design. It’s important these devices are flexible because if they’re to stiff the made lead to damage to the blood vessels or cause blood clots.
The lab I worked in made a special stem cell treatment to heal broken bones. We used this to heal the leg bone of a dog (Eva) that wasn’t able to heal itself. The dog would have had to have the leg removed but they tried our special treatment and it worked! Eva is still happy and running around so we were all delighted.
I really enjoyed my Leaving Cert projects – first was a carousel, then I repeated and did Engineering again to make a crane. This combined mechanical and electrical, and was my first real experience in designing and manufacturing
I really like the humerus that I 3D printed and also the screws because of how detailed they are. I was also able to 3D print an airplane on a stand which was also very cool!
Recently, I developed a wristwatch-based wireless device, that I like the most. This device has integrated sensors for heart rate, temperature, and blood oxygen saturation level measurements and can be used for wireless monitoring of patients’ health conditions in a hospital.
