Presto and T&W Engineering Announce Long-Term Partnership to Advance Wearable Brain Sensing

Meyreuil, FranceNovember 2, 2023—Presto Engineering, a European leading expert in application-specific integrated circuit (ASIC) design and semiconductor engineering and production services, and T&W Engineering, the leading in-ear electroencephalogram (EEG) wearable device developer and provider of artificial intelligence (AI)-driven EEG reading services, today announced their collaboration to develop an ASIC for measuring high quality, multi-channel dry-electrode EEG for next-generation wearable brain sensing.


T&W Engineering has researched and developed in-ear EEG technology for more than 10 years and has published a significant amount of peer-reviewed scientific articles and patents in collaboration with academic and scientific partners. By leveraging the competencies as a spin-out from one of the world’s largest hearing aid manufacturers, T&W Engineering is advancing patient-centric brain sensing by integrating dry-electrodes and advanced miniaturized electronics into a pair of in-ear headphones. The potential applications are vast, with an immediate focus on digital biomarkers for assessment of sleep, epilepsy and neurogenerative disorders such as Alzheimer’s and Parkinson’s diseases. The development and partnership with Presto, a company recognized for its track-record in the manufacture and supply of ASICs for hearing aids and wearable devices, will enable T&W Engineering to release its new, innovative product with the highest quality and ensure superior patient care.

T&W Engineering’s in-ear EEG technology provides a user-friendly, scalable and long-term sensing solution in the patient’s natural environment. For healthcare providers, the technology enables improved insight in the assessment of brain health.


According to Cedric Mayor, CEO, Presto Engineering, “Our collaboration with T&W Engineering is the perfect synergy of our respective strengths. Without leveraging T&W Engineering’s expertise in wall-to-wall design of medical products, combined with Presto’s capabilities in semiconductor design, industrialization, production test and supply chain management, such breakthrough innovation will be difficult to hit the market first-time right. Releasing exceptional and innovative ASICs is what we strive for. We are grateful to T&W Engineering for such a rewarding opportunity to contribute to improving patients’ lives.”


Richard Topholm, CEO, T&W Engineering, also shared his thoughts on the partnership, saying, “We are thrilled to collaborate with Presto once again, a trusted partner who shares our commitment to advancing medical solutions. Our combined capabilities enable us to tackle complex challenges and drive innovation in the healthcare industry. Together, we aim to make a significant impact in the field of EEG technology and improve the lives of individuals affected by neurological disorders.”


Presto and T&W Engineering remain dedicated to their shared goal of enhancing patient care through innovative solutions. This long-term partnership represents a powerful alliance that harnesses the strengths of both companies to deliver cutting-edge products for healthcare.

About T&W Engineering

T&W Engineering is focused on simplifying brain sensing for everyday use. We strive to enable device and data augmented applications across the health continuum, from healthy living and prevention, to diagnosis, treatment and home care, partnering with top applications specialists and researchers across the world. Formed in 2015 as a spin-out from Widex, we leverage 65 years of experience in medical ear-worn technologies, and pioneer the use of long-term EEG, deep clinical insights, and advanced machine learning to deliver on the promise of ubiquitous brain sensing.

Since 2006 we have researched and developed the technology for Ear-EEG as well as many of its applications; and are the leading developer of this novel technology. Ear-EEG is a novel way to measure brain-activity without the traditional cumbersome EEG setups. This allows discreet and easy unassisted brain sensing, enabling a host of new applications, such as sleep-analysis, epilepsy, brain-computer interfaces, stress, depression, and neurological disorders.

In short, “Brain sensing made easy!”
