About
We are Praxa Sense, a young medtech start-up working on the development of an innovative, data-driven device that enables patients to monitor their vital signs at home. We enable data collection over the long term, helping the medical professional to diagnose diseases earlier. Our goal is to improve the medical processes by making products that perfectly combine hardware, software and user experience. We are also developing our own sensor in-house which could optimize some of the existing hardware out there. For this project, we are looking for an intern who likes a technical challenge.
Internship Opportunity
We are looking for a student who is interested in performing optical experiments/investigations related the development of our (new) non-invasive sensor. The sensor functions comparably to a photoplethysmography (PPG) sensor, and is hence configured to measure cardiac flow in a non-invasive manner.
The student will be tasked with designing different optical configurations of I/O components required by the novel sensor to investigate several sensor parameters. This will include writing measurement plans and constantly updating/redesigning prototypes. A certain autonomy is required during the internship; the student should be able to interpret obtained results, and use made conclusions to make new plans/prototypes.
The I/O components are ready to use, and designed to allow for an easy implementation into different configurations. Prototypes will either be fabricated in a lab-environment using specialized optical equipment, or be fabricated using a 3D-printer (wearable applications), hence an affinity with optical instrumentation and modeling software is considered a strong plus.
Background
In PPG technology a LED and a photodiode are used to measure changes in blood volume. These volume changes are the direct result of the heartbeat and the saturation level of the patient. Through these changes the heart rate of the patient can be measured. In our newly designed sensor, we optimize this process by replacing some of the hardware which enables the removal of motion artifacts usually plaguing PPG measurements thus improving the accuracy of heart-rate measurements. The approach is both novel and supported by research from the TU Delft.
What we offer
- A young and professional yet fun team
- Lots of freedom to implement your ideas
- Opportunity to be hired after the internship or after your study
- Internship compensation gross €400 per month
What we ask
- Bachelor/Master student in Physics and Mechanical Engineering or a comparable field.
- An interest in biophysics and healthcare is recommended.
- Proactive team player with good communication skills
- Experience with Python and/or Linux is a plus.
