Applications in medical technology include development and quality assessment of medical instruments like micro-fluidic devices, dental descalers, surgical instruments, and medical imaging devices. Further, there are many medical, safety and health-care devices like inhalers, respirators and toothbrushes that have been investigated using Polytec vibrometers and white-light interferometers.
Visualizing the motion of ultrasonic dental descalers is challenging due to their high-frequency vibrations and small associated displacement amplitudes. Laser vibrometry has made it possible to study, in detail, the vibration patterns of dental ultrasonic descaling equipment, and to determine which may be the most effective designs.
At Pari GmbH, one of the leading manufacturers of aerosol generation systems in Germany, the quality of the nebulizer systems is 100 % verified using a Compact Laser Vibrometer. The quality of a key element of the nebulizer system is ensured by measuring the vibration characteristics of the membrane generating the aerosol.
A motor for nano-robots is being developed with the help of Polytec’s Micro System Analyzer. Its Australian creators hope their tiny motor – which is less than the width of three human hairs – will soon power medical nano-robots that can swim through tiny blood vessels into the brain. View video >>
