This in-ear thermometer can help you get pregnant

YONO keeps fertility tracking, natural family planning and hormonal health monitoring simple.

With one in eight couples experiencing difficulties when trying to conceive a child, Bay Area startup Yono Labs wanted to develop an easier, more accurate way to help women track their fertility. Based on her own experiences when trying to get pregnant, company founder Vanessa Xi found the process to be very stressful. In an effort to successfully procreate, women today can use technology to collate data and identify optimal times where they are most fertile. However, acquiring such information can be quite the hassle. Women must manually record a variety of different symptoms in order to determine whether they’re ovulating.


One of the most common data points is the Basal Body Temperature (BBT), or the lowest temperature of a body in a 24-hour period. Collecting the BBT, though, requires a woman to take her temperature as soon as she first wakes up in the morning and at the same time every day. As you can imagine, this is rather frustrating and throws in the element of human error. And so, Xi decided to create a more effective, streamlined way to obtain these numbers. How, you ask? With an in-ear wearable thermometer that captures true body temperature instead of skin temperature, allowing women better manage their ovulation cycles.

As a woman sleeps, the silicone-encased YONO comfortably sits in her ear canal and measures her real basal body temperature — usually occurs between 2-6am — without being affected by the ambient temperature. Unlike other basal thermometers on the market, the device will take its wearer’s temperature up to 70 times each night.


When not in use, the earbud is stored in what’s called a “Base Station,” where the data is then transferred over Bluetooth and synced with the YONO iOS or Android app. There, the data is analyzed to provide the user with a breakdown of her pattern to determine the best fertility window to make a baby. And for family planning purses, knowing the pattern can help prevent unplanned pregnancies as well.

The wearable is equipped with a tiny Atmel MCU and a Bluetooth module, both housed inside a silicone shell that comes in three different colors (bright green, violet and sea foam).


Thinking about having a child? Take the stress out of the process with YONO! You can start by heading over to its Kickstarter campaign, where its creators have just surpassed its goal of $30,000. The first batch of units is expected to ship later this year.
