As part of his final year project in his Masters degree in Electromechanical Engineering, which he studied at the University's School of Electronics and Computer Science (ECS), Fauzan Baharudin explored the potential for the use of thick film technology in the development of medical sensors which could be embedded in the knee during surgery.
This new sensor, called Serial In-vivo Transducer (SIT), which uses thick film technology, could measure tendon force during Anterior Cruciate Ligament (ACL) reconstruction.
The ACL is the most commonly injured ligament and is commonly damaged by athletes, in fact it is reported that this is the ligament associated with Tiger Woods’ injury.
Fauzan’s project was supervised by Professor Neil White at ECS, who, in 1991 developed thick film piezoelectric material which made it possible to produce a sensor which could power itself if it were installed in a device that vibrates and would be ideal for appliances where physical connections to the outside world were difficult.
Professor White said: ‘Although this work is still in its infancy, our earlier research in thick-film sensors has shown that it is feasible to apply the technology to medical applications such as prosthetic hands. We have also shown that it is possible to harvest energy from the human body using piezoelectric materials and the knee is subjected to very high levels of force during everyday activities. It therefore seems logical to combine the two approaches to deliver a new type of embedded, self-powered sensors
In Fauzan’s project entitled Assessing the use of thick-film technology in knee surgery: along with energy harvesting in-vivo, he has also incorporated some of this energy harvesting capability into SIT which means that it will be self-powered.
'I chose knee surgery because this has been very little research carried out in this field and I felt a self-powered device could work well in the knee,' he said.
Before developing SIT, Fauzan reviewed the existing devices in this field and concluded that due to its flexibility in fabrication, low capital cost, fast lead time and its suitability for use in the body, thick film technology is the best solution for ACL surgery. Assessment of the energy harvesting feature revealed that the device could produce more than enough energy to power itself.
'It remains a mystery to me, given how common knee injuries are among athletes, that devices like ours have not been developed before now,' said Fauzan. 'A sensible assumption for this is that thick film technology does not reach medical researchers as quickly as it does within the microelectronics community hence the delay in realising the huge potential in developing in vivo transducers.'

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
