Ora Graphene and Merry Electronics to soon ship off-the-shelf premium graphene-based headphone drivers

Ora Graphene, producer of free-standing graphene membranes, announced a partnership with Taiwan-based Merry Electronics to develop off-the-shelf GrapheneQ headphone drivers. These, according to Ora, will be the world's first commercially available graphene-based drivers. The two companies will offer 40 mm and 50 mm drivers, which will be available for pre-order in Q1 2024.

Ora Graphene says that it already integrated its technology into flagship products for two major consumer electronics companies - both of these premium gaming headphones. The availability of off-the-shelf headphone drivers will hopefully accelerate the adoption of Ora's technology.

Q: Thank you for this interview Roberto! Very nice to e-meet you. We know you have been involved with graphene research for some time, can you give us a quick overview of your graphene research interests and projects?

Thank you for the opportunity to discuss my research. Within the Graphene Flagship's Work Package 6 (core 3), my primary focus lies in integrating graphene into sensors, particularly microphones. My main objective is to develop methods that enable the seamless integration of graphene on a wafer-scale while thoroughly exploring the advantages and disadvantages associated with such approaches.

In addition to developing fabrication techniques, I am also highly interested in characterizing the potential of graphene for acoustic devices. This type of research plays a crucial role in bridging the gap between graphene's exceptional properties and its practical utilization in the industry, unlocking higher performance and new sensor concepts.

Haydale supplies graphene materials for audio equipment by Rega Research

Haydale has announced it has supplied audio equipment manufacturer Rega Research ("Rega") with its mechanically enhanced prepreg for improved sound quality on its latest turntable.

Using Haydale's HDPlas technology, the graphene-enhanced prepreg has been applied into the manufacturing process for Rega's award-winning turntables. The mechanically enhanced prepreg has been combined into the stressed skin design of the plinth and bonded to the core material to increase the stiffness of the part by 11% reducing resonance and improving sound quality.

Ora Graphene announces a strategic investment to advance existing graphene endeavors and explore additional application areas

Ora Graphene, producer of free-standing graphene membranes, has announced the closing of its CAD$3 million (around USD$2.46 million) Seed financing round. The deal was led by Ecofuel Fund along with Export Development Canada (EDC), BDC Capital and certain members of New York Angels. Existing investors TandemLaunch, and BoxOne Ventures also participated in the round. In conjunction with the financing, the company was recently awarded a Sustainable Development Technology Canada grant to explore new areas of graphene applications for its technology.

Ora has produced what it refers to as 'the largest sheets of free-standing graphene demonstrating incredible new material properties for multi-purpose commercial utilization'. GrapheneQ membranes have already been shown to significantly improve sound quality and reduce energy consumption for global manufacturers of consumer electronics, with applications being developed for exciting new markets opportunities.

Penn State team applies 'magic angle' graphene to acoustics

A team of Penn State researchers has designed an acoustic equivalent of magic-angle bilayer graphene. Two graphene sheets stacked on top of each other, called bilayer graphene, exhibit unique properties when one of the layers is twisted at a certain angle — a magic angle. The study of magic and other angle misalignments between two layers of material and their effects on material properties has been dubbed twistronics, a rapidly expanding field of condensed matter physics.
