Medical technology is developing rapidly and microfluidics contributes to a large part to it – it is seen as a future technology and is the key to many high-tech applications that are used for diagnostics and therapy.
Microfluidic applications can benefit enormously from the properties of piezo technology – thanks to their compact size, high speed, accuracy, and their low energy requirements, piezo ceramics can be used in numerous applications.
High-precision dosing systems, which are operated by piezo ceramics, can generate several thousands of picoliter droplets per seconds. This high throughput, for example, is indispensable for array plotting in manufacturing lab-on-a-chip systems or for consumables for in vitro diagnostic (IVD) tests.
Furthermore, piezo elements are readily used in liquid handling in IVD instruments, e.g. for PCR tests. They can dose, move, and mix tiniest liquid volumes with differing properties with high precision.
Piezo elements are convincing in dosing systems, such as micropumps for insulin or pain medication, thanks to their precision and their small size and low weight. This makes it possible to produce systems that are small, lightweight, and easy to handle; therefore, making it easier for the patient to manage their application.
