T&W Engineering has dedicated over a decade to researching and developing in-ear EEG technology, producing numerous peer-reviewed scientific articles and patents through collaborations with academic and scientific partners.

As a spin-out from one of the world’s largest hearing aid manufacturers, T&W Engineering focuses on patient-centric brain sensing by integrating dry-electrodes and advanced miniaturized electronics into in-ear headphones.

The potential applications for this technology are extensive, with an initial focus on digital biomarkers for assessing sleep, epilepsy, and neurogenerative disorders like Alzheimer’s and Parkinson’s diseases. By partnering with Presto Engineering, a company renowned for its track record in manufacturing ASICs for hearing aids and wearable devices, T&W Engineering aims to ensure the release of its innovative product with the highest quality and superior patient care.

T&W Engineering’s in-ear EEG technology offers a user-friendly, scalable, and long-term sensing solution in a patient’s natural environment, providing healthcare providers with improved insights into assessing brain health.

Cedric Mayor, CEO of Presto Engineering, expressed the significance of this collaboration, stating, “Our partnership with T&W Engineering perfectly combines our respective strengths. Without leveraging T&W Engineering’s expertise in designing medical products from the ground up, along with Presto’s capabilities in semiconductor design, industrialization, production testing, and supply chain management, it would be challenging to introduce such groundbreaking innovation to the market. Releasing exceptional and innovative ASICs is our primary goal, and we are thankful to T&W Engineering for this opportunity to enhance patients’ lives.”

“We are excited to work with Presto once again, a trusted partner who shares our commitment to advancing medical solutions. Our combined capabilities allow us to address complex challenges and drive innovation in the healthcare industry. Together, we aspire to make a significant impact in the field of EEG technology and improve the lives of individuals affected by neurological disorders.”

–Richard Topholm, CEO of T&W Engineering
