Leveraging EEG sensors and generative audio, these earbuds aim to enhance sleep quality through personalized neuro-adaptive stimulation.


Summary: IDUN Technologies and SEGOTIA are collaborating to create innovative earbuds that use neuro-adaptive audio technology to improve sleep quality. By embedding EEG sensors in the earbuds, they can monitor brain activity in real-time and use generative audio to stimulate the brain, promoting relaxation and deeper sleep. This project is funded by a Eurostars grant and aims to develop a comprehensive hardware and software platform for commercialization.

Key Takeaways:

  • Neuro-Adaptive Technology: The earbuds utilize EEG sensors to monitor brain activity and generative audio to actively stimulate the brain, enhancing sleep quality by promoting relaxation and increasing time spent in deep sleep.
  • Collaborative Development: The partnership between IDUN Technologies and SEGOTIA, supported by a Eurostars grant, focuses on developing a reference platform that integrates advanced brain-sensing and audio technologies for next-generation sleep enhancement solutions.
  • Broad Applications: Beyond sleep improvement, these earbuds have potential applications in reducing daytime fatigue, enhancing focus, managing sleep-onset insomnia, and supporting individuals with sleep disturbances, offering a non-pharmaceutical solution for better sleep quality.

IDUN Technologies and SEGOTIA have partnered to develop earbuds that use brain-sensing technology and generative audio to improve sleep, backed by a Eurostars grant.

IDUN Technologies currently has a version of brain-sensing earbuds currently in the market. Now, the company will use non-dilutive funding from Eurostars to develop a sleep-specific solution with Segotia, a provider of audio digital signal processing and neuroscience to IP providers and manufacturers of consumer audio products around the world, that will actively stimulate a user’s brain to enhance sleep and focus.

“By combining brain activity monitoring with acoustic modulation, our earbuds offer a personalized and effective solution to enhance sleep and overall well-being, addressing a global health concern and improving the lives of millions. We look forward to advancing this exciting technology and bringing its benefits to the consumer market,” says Simon Bachmann, co-founder and CEO of IDUN Technologies. 

Using proprietary EEG sensors embedded in earbuds, electrical activity emitted by the brain can be used to monitor the brain’s state, while real-time generative audio can be used to encourage the brain to move to or maintain a particular state. The project’s goal is to develop a reference hardware and software platform to provide closed-loop auditory neurostimulation and embed this technology into an earbud that can be scaled with commercialization partners.

By embedding EEG sensors in the earbuds, the brain’s electrical patterns can be monitored in real-time and deliver personalized audio stimuli to encourage the brain to shift into optimal sleep states. This technology aims to improve sleep quality by promoting relaxation, reducing stress, and increasing the time spent in deep sleep.

Project Roadmap and Development Areas

The project roadmap extends across multiple activity areas:

  • Neuro-Audio Dataset: Collection of in-ear EEG on human participants with audio to provide an understanding of how different audio manipulations influence neuromarkers and behavioral outcomes relating to focus and relaxation.
  • Mobile App: A mobile app interface will be created that allows users to see their brain metrics and dial in the relaxation or focus state they would like to achieve.
  • Brain State Engine: Real-time EEG signal conditioning and neuromarker extraction to infer user brain state.
  • Generative Audio Engine: Low-latency, high-efficacy audio generation engine that receives feedback from the neuro layer and can be integrated into advanced wireless earbud hardware.
  • Neuro-Audio Logic Layer: Customization of algorithms to enhance focus and sleep for users. This software layer will run between the generative audio engine and brain state engine at the edge and adapt the generated audio to the needs of the user.
  • Reference Design: The hardware design of the neuro-adaptive audio platform includes ear-tip sensors, a bio-potential amplifier and an edge-processing chip with wireless audio, packaged for OEM customers to integrate into their hearables products.

Expanding Applications

Beyond enhancing sleep, the earbuds have several promising applications, according to Bachmann. They can help fight daytime fatigue by supporting napping and improving focus throughout the day, which has implications for workplace safety, especially in industries where fatigue can lead to serious accidents. 

Additionally, the earbuds can be used to manage sleep-onset insomnia, maintain continuous sleep, and support waking functions, as well as benefit individuals with sleep disturbances, such as insomnia or sleep apnea, by providing a non-pharmaceutical solution to improve sleep quality.

The development project, which runs for 24 months, started in April.
