Q-strip quantitatively measures sweating during sleep.

What is the Q-strip?

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.

Paper & Carbon

The Q-strip ribbon includes two electrodes that measure the resistance between the electrodes and transfer it to a moisture sensor connected to a Printed circuit board (PCB).

Science of Data

At the moment we are cooperating with different medical scientists to validate the Q-strip as a new digital biomarker. In meantime we collect more data from our network.

The Things Network

We are using the LoRaWAN protocol to connect with The Things Network and capture the data from our sensors. TTN provides a set of open tools and a network to build IoT applications.

It took me almost 2,5 years to get the sharpest data out of a Q-strip during development. To give you an idea: each test ride is 1 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 tried it on… For me, it’s ready enough to show the world my discovery, my personal hardest work of development ever.

Our mission with Q-Strip

We have been developing the Q-strip for more than three years. We are testing and optimising the Q-strip for measuring sweat values at night. We see both daily and multi-day patterns in the data that we cannot explain.

We believe in the potential of the Q-strip for a variety of purposes. We dream that Q-strip will become an instrument that can be used for medical purposes.
