Hi! How did you sleep last night? Did you use the lateral position?

Today we will talk about one of our new product’s unique designs: automatic magnetic switch.

As we discussed in recent posts, the product is composed of the PU sphere and electronic component, which will vibrate to notify users when they are on supine positions.

So how to turn this device on and off?

Our solution is the automatic magnetic switch. When the two parts of the sphere attach through magnetic force, the imbedded chip will be activated.

Meanwhile, the gyroscope starts to work to detect position movements.

The algorithm learns whether you are heading to sleep or remove the device as you wake up. The device will accordingly start to work or remain the sleep status.  

Just like Go2sleep, this device does not have a physical switch either and that’s because SLEEPON aims at bringing the best user experience to our customers. You don’t even need to bother switching it on and off.

Do you like this design?

Hardware Almost Finished!

Hi everyone, how did you sleep last night?

We want to share with you that the hardware part of our new product Go2silence is almost done!

Go2silence is composed of electronic components and the PU sphere, which are connected through a strong magnetic force.

Before you sleep, put the part with sensor on your back inside pajama and place the other half outside. The two parts will match and “stick-on” your clothes.

The unique material and craft will not cause the cold feelings that other metal surfaces may bring. The elastic sphere will provide you a comfortable user experience without waking you up abruptly.

Here are some of the product details:

Weight: 57 grams /0.13 pounds

Diameter: 6 cm/2.4 inches

Charge method: Type-C charger (130mah). Charge one time to use for one week.

We will start to prepare some prototypes for clinical trials. And if you have any idea or feedback, feel free to leave a message at We appreciate the feedback received recently regarding product size, design, and other new R&D directions.

anti-snoring, snoring

Demystifying the Development of Go2silence— Log 6

Hi everyone, how did you sleep last night?

Our R&D process of the anti-snoring product is well on track and we have made some significant progress.

As shown in the design manuscripts below, the hardware is composed of two parts. One is a soft sphere made of polyurethane foam aims to prevent supine positions. The other part is made of the battery and a circuit board wrapped by aluminum to monitor sleep positions and vibrate when the user is on supine position. The sphere will be placed outside of the clothes and the electronic part placed inside when used. The two components will be attached through magnets.

The current sample is the 7th generation after adjusting the look, hardness, weight, surface, magnetic force, and many other factors.

We picked 6 testers who are healthy and have no snoring symptoms to let them test the sample at night:

1. Detachment test

Five out of the six testers reported that the sample did not detach from the t-shirt and one tester tried to move vigorously just to see under what cases will it fall. Based on this result, the sample would not detach from the clothes easily and we will further verify that in the future.

2. Comfortability test

Three testers said that the weight of the ball created an uncomfortable feeling. Two reported that if feels cold when the body touches the aluminum surface. And one said that since he normally lies flat, he feels uncomfortable if forced to use lateral position. Our engineers have started to make some adjustments based on the above feedback.

We also found that as most of the testers sleep on a soft mattress, when lying flat, the feeling of having a ball underneath would not be that uncomfortable, but it would be different if the bed is harder. We also detected some issues regarding details such as the gap was a little large or the logo effect was not perfect. We will tackle these later and the current sample has given us much confidence for future improvements.

Next, we will focus on all the details of the hardware, firmware, software, and app animation to create an optimal user experience.

Thank you for following us and more development stories on the way!

anti-snoring, snoring

Demystifying the Development of Go2silence — Log 7

Hi everyone, how did you sleep last night? We have finished the app design of the new anti-snoring device. Let’s take a look!

1. Add New Device

Users can add SLEEPON devices in the app.

Go2sleep users can now add the second device as shown.

Since the two products have data overlap (e.g. anti-snoring ball can also measure sleep duration, … etc. using iOS Health function), you can adjust the data source priority by sorting devices as shown in the graph.

2. Device Setting

Here are more settings for the anti-snoring ball.

As this product is designed to prevent supine positions, you can turn on the vibration alert that will notify you to change sleep positions.

You can also set the sensitivity of the device. Higher sensitivity will make the device notify you at positions close to the supine position.

3. Real-time Views

Go2sleep users can see the sleep position label after the real-time label.

You can see detailed info after clicking the position label. After click on the sleep position label, you can check your real-time sleep positions

4. Sleep Report

We offer three report views, which are playback, label, and detailed chart views.

Any feedback on our software and app display?

Data Integration Design

Hi everyone! How did you sleep last night? In the past ten days, we were trying to solve another main problem——how to incorporate data of this new SLEEPON product into the sleep report? 

Our current sleep report shows detailed stats collected by the Go2sleep ring. As shown in the pictures below, there are different sleep labels in the app categorizing various sleep information. 

But for our users who only buy the anti-snoring device, what kind of report will they get? Only see whether they snored or not? Definitely no. We want our users to learn more about their sleep condition even though they have not purchased the Go2sleep ring.

Our solution is to first establish another data source and then rank data accordingly.

For example, the health function of the iPhone and Android systems can also collect data about sleep duration and sleep cycle. It is not as accurate as the ones detected by Go2sleep rings but can provide users some reference. The SLEEPON app will thus import and add the data into the sleep report. If users use both the anti-snoring device and Go2sleep, the system will prioritize and only show data from Go2sleep in the report.    

Our engineers are working on the new app version which will be available soon!

An Exciting Feature.

Hi everyone! If you read our last post, did you use a lateral sleeping position? We hope so!

Our development of the anti-snoring device has achieved quite solid progress. But in the beginning, we had two different opinions about the development direction. The first idea is to create a digital device with the ability to present sleep position data but also high costs. The second view is to produce a low-cost non-digital product purely based on Positional Therapy. We finally chose the first plan as we believe sleep position data can help users better understand their sleep conditions.

Just the next day, our product engineer had a stunning idea! He planned to use 3D animation to create sleep position simulation. Users can watch their position changes in the app the next day after wake up. The whole team thought the idea was brilliant and if realized, this device will probably be the only product (except using cameras) with the function of sleep position playback.

We have three product teams.

Team 1 takes charge of industrial design, CMF (color, material & finish), and mechanical design.

Team 2 is responsible for the development of PCBA (Printed Circuit Board Assembly) and embedded software & algorithm.

Team 3 works on the app page and backend.

Thus, the task of building sleep position playback function was given to team 2 and 3. Team 2’s goal is to accurately collect every position data using gyroscope sensors. We welded a three-axis gyroscope to the PCBA and input battery to make it a simple motion tracker.

Placing the simple device on the tester’s back, our engineers then read collected data the next day and examined ways to improve. After weeks of testing, we were able to separate sleep position data accurately.

Team 3 works on animation modeling and this position simulation is quite challenging for our front-end engineers. Issues include how to create the animation and how to match animation with sensor data of every minute. Thanks to their learning abilities, they finally found solutions and kept refining the animation as shown in the graph.

There is still a long way to go for the final version of this anti-snoring device with the function of sleep position simulation. Follow us for future news and development stories!

Choose the right material

Hi everyone!

Last time we discussed how sleep experts proved the effectiveness of Positional Therapy. We can see many people DIY their PT items and most of them sew a tennis ball on the back of a T-shirt.

If lying on the back, people will get uncomfortable due to the tennis ball and thus change to a lateral sleeping position. We made some of those as well and called them “anti-snoring pajamas”.

But this is still far from a real product and we recognized two key points to be worked on:

1. Weight.

New users of the “anti-snoring pajama” may not be used to the feeling of having something pulling the clothes during sleep. They may get used to the weight of the tennis ball later, but we want to find out what is the best weight of the PT product.

2. Hardness.

If the ball attached on the back is too hard, users will get uncomfortable. Whereas if it is too soft, there will be no anti-snoring effect. Thus, we need to figure out what is the best hardness.

We first tried the cork material to test the anti-snoring effectiveness. Even though the cork ball is 15g lighter than the tennis ball and reduces discomfort, it has relatively higher hardness and we had to look for other choices.

We then tried other materials with different hardness and weight. We also visited an engineering library with hundreds of different materials.

After months of trials, we finally chose the polymer composite foam (polyurethane foam), which is a lightweight foam material with adjustable hardness (shown in figure). It is also suitable for the molding process of production.

As we find one answer, we still need to address many other questions during the R&D process. Should we keep using the shape of a sphere? What else can we do to improve sleep and snoring? How to quantify and visualize the improvement of snoring? These questions will be answered one by one in future posts. Follow us to join the journey!

Wish you have a good dream tonight.
