Nocturnal sweat rate sensor

Q-strip quantitatively measures sweating during sleep.

The Q-strip is a ribbon that quantitatively measures humidity. The ribbon includes two electrodes that measure the resistance between the electrodes. The values are transferred to a moisture sensor that is connected to a Printed Circuit Board. The PCB forwards the data sequentially to a database.

Sweating is known as a symptom of many diseases. Our mission is to develop an easy to use device for measuring and analyzing nocturnal sweating for medical purposes.

Use of the Q-strip in a bed

It took me nearly 3 years of development to be able to measure the accurate data we have now. To give you an idea: each test ride is one night of test time and preparation. I developed over 73 different types of Q-strip prototypes with different calculation methods and around 8 types of materials. Not to forget the 15 different types of boards I’ve used during development. I am ready to present the world the best product I have ever developed: the Q-strip!

Our mission with Q-Strip

The Q-strip sensor can be used for a variety of purposes. At the moment we are testing and optimising the Q-strip for measuring sweat values at night. Our dream is that Q-strip will become a digital biomarker that can be used for medical purposes.
