AT - Case study topics Group 1 – Cancer detector For many diseases it is very important to detect them in an early stage, so they can still be treated successfully. A person’s breath can contain small particles, which indicate the possible presence of lung cancer. Sensors are being developed to perform such early stage diagnostic in which the sensitivity of a piezoelectric element is crucial. A promising material is lead zirconate titanate (PZT). Group 2 – Self-cleaning surgical tool Environmental disinfection plays a crucial role in the prevention of infectious diseases. In hospitals anti-bacterial treatment is a very crucial procedure to keep everything sterile. Self-cleaning surfaces on surgical tools are formed by coating with a photocatalytic material. A promising material is TiO2. Group 3 – Hydrogen fuel cell car Hydrogen fuel cell cars are zero emission and run on compressed hydrogen fed into a fuel cell stack that produces electricity to power the vehicle. Solid oxide fuel cells use high tech ceramics as the electrolyte, which enhances efficiency and stability but presents a challenge in terms of temperature. A promising material is YSZ. Group 4 – Microbattery for medical implant Common rechargeable batteries are based on a liquid electrolyte, which implies that there are several restrictions for their design and size. Secondly, they carry the inherent risk of leakage. Therefore, the need for all-solid-state microbatteries arises, which can facilitate miniaturization, will create more flexibility for the design of standalone microelectronic devices and enhance their applicability, for example in medical implants, due to the avoided leakage risks. A promising material is LiCoO2.
