Stage-Event:Vibration perception of a Sonicare Powered Toothbrush

Geplaatst op: 15-04-2019 | Solliciteren voor: 01-01-2020


Vibrating medical devices or self-care appliances are abundant on the market; however, the study of human vibration perception is a relatively young science and there are still many knowledge gaps related to perception measurement.

This assignment is focused around the perception of hand-transmitted vibrations when using an electrically- powered toothbrush. The perception of these vibration via receptors in the human skin is strongly dependent on the amplitude and frequency of the stimulus signal, but also on aspects like the firmness of the grip and contact area. We’re looking to expand our knowledge in the field of vibration perception.

Your challenge is to further develop existing or new measurement methods for the quantification of vibration perception. The overall goal is to gain a deeper understanding how the quality of a powered toothbrush can be influenced during the product development.


Research and experiment with different methods of measuring vibration

Performing engineering tasks and problem-solving activities related to the development of novel measurement techniques for vibration quantification using acoustic holography

Ability to work well in a multidisciplinary team environment

Current enrollment in a Biomedical Engineering/Physics degree-seeking program at the Bachelor’s or Master’s level.

Period: 6 months for 1 person
