Researchers who operate in South Korea have designed a polymetric sensor. This is on a radiofrequency ablation surgical needle and it is designed to monitor both temperature and pressure in real-time. The sensors have been integrated into a needle tip and it is said that this has really helped to rocket the efficacy. This has worked very well in clinical tests and experts have now said that they have the chance to practice safer and much more effective methods of practice. RFA is very minimal in terms of how invasive it is and it is also designed to remove any kind of tumour. It's also great for treating cardiovascular disease. When the procedure is carried out, an unintended and audible steam can pop due to the pressure being ablated. When the team at the KAIST company were asked about this, they have discovered that it was a combination of the negative and thermal effects on the tissue. Those who are seeking engineering jobs will find this very interesting.

The professor at KAIST, who is Inkyu Park has stated that his team have sensors that are very reliable and they are also able to detect the occurrence of steam pop too. The sensors have been able to monitor the hot steam in the tissue rapidly and it is expected that the diverse properties could easily be checked by utilising the physical sensors. This has all been integrated into the needle. They believe that the sensors can provide a huge range of information about the medical procedures that are required as well as helping to document any environmental changes that may happen in the human body. This is effective and it is safe for surgical procedures, which is amazing to say the least. It also goes to show how far things have come over the years too.
