Evaluation and Selection of a Protective Microphone Membrane
Master's or Bachelor's degree in Engineering (15–30 ECTS).
About Precision Pulmo
Precision Pulmo is a Swedish deep-tech company based in Linköping, developing a new platform for the objective measurement of respiratory function. Our technology derives airflow characteristics from the sound generated by the air itself, using advanced signal processing without any moving mechanical flow sensors. This enables measurements during natural breathing, even in patients who cannot follow breathing instructions.
Our first product, Equinspire, targets equine veterinary medicine. It is a portable, non-invasive solution designed for use in clinics and stable environments, enabling objective respiratory monitoring over time.
Background
Our microphones operate in demanding environments exposed to dust, moisture and ammonia, as well as frequent cleaning. They must be protected by a membrane that provides sufficient environmental protection while having minimal impact on acoustic performance. Finding the right balance is critical to measurement quality.
The project includes
- Define requirements for acoustic performance, environmental durability, hygiene and manufacturability.
- Investigate suitable membrane materials, such as ePTFE, silicone, polymer films and technical textiles.
- Develop a test setup to measure frequency response, signal attenuation and noise, and evaluate resistance to dust, moisture and cleaning agents.
- Compare the candidates using a weighted decision matrix and recommend the most suitable membrane.
We are looking for students in
Engineering physics, materials engineering, mechanical engineering, electrical engineering or acoustics.
