Since the very beginning of eye movement research, the kinematics of eye movements has been investigated with a variety of measurement techniques: suction contact lenses (Yarbus, 1967), scleral search coils (Robinson, 1964 Fuchs, 1967), electro-oculography (Becker & Fuchs, 1969 Baloh et al., 1975), limbus tracking (Stark et al., 1962 Bahill et al., 1975). When scanning the surrounding environment, human eyes make two to three fixations per second and move very quickly between each fixation with a saccadic eye movement. This framework lays the foundation for a normative dataset of healthy oculomotor performance for the assessment of oculomotor dysfunctions.

The method has been released as a software toolbox for public use. The designed experimental procedure is natural and non-fatiguing, thus it is well suited for fragile or non-collaborative subjects like neurological patients and infants. The obtained measurements are characterized by high repeatability, allowing for fine assessments of inter- and intra-subject variability, and inter-ocular differences.
In this work, we propose a novel approach for standard indicators of oculomotor performance. Despite its significance, there is no general methodological consensus for reliable and repeatable measurements of the main sequence. Deviations of eye movements from the main sequence can be used as markers of specific neurological disorders. Their kinematics is well defined, showing regular relationships between amplitude, duration, and velocity: the saccadic ’main sequence’. “Increasing panel efficiency and shifting to more abundant materials before constraints on silver and other materials limit industry growth is critical to improving the uptake of solar PV in Australia and around the world,” he said.Saccades are rapid ballistic eye movements that humans make to direct the fovea to an object of interest. Virescent Ventures managing partner Ben Gust said SunDrive’s technology has the potential to be the leading method for silver replacement in solar PV production. SunDrive is thrilled to now be working with Australia’s top deep tech and cleantech investors in developing next generational solar technologies.” “Australia has arguably made the greatest scientific contribution to the development of solar technology, having invented the technology behind 90% of all solar panels made worldwide.
“The use of silver is the common denominator and is holding back the rapid advancements needed to transition to a solar powered electric world,” he said. Last year SunDrive set a new world record for solar efficiency, taking the title from the Chinese.ĬEO Vince Allen said that in order to decarbonise, solar cells need to be more efficient, cheaper and scalable than they are currently. Government-owned Australian Renewable Energy Agency (ARENA) has also tipped $3 million into the venture two years ago.

Existing backers and Atlassian founder Mike Cannon-Brookes once again invested through his family VC, Grok, along with Blackbird Ventures, while Canva founder Cameron Adams, former PM Malcolm Turnbull and Tesla chair Robyn Denholm made first time bets on the tech.ĭenholm joined SunDrive’s advisory board last year.īlackbird originally backed SunDrive’s seed round in 2018, and founding partner Niki Scevak joined the startup’s board in 2020 following a $5 million Series A.
The raise was led by the CSIRO’s VC fund Main Sequence Ventures, with the federal government’s Clean Energy Finance Corporation chipping in $7 million through its Innovation Fund, managed by Virescent Ventures. Copper is nearly 100 times cheaper than silver and far more abundant. The solar PV industry already uses around 10% of the world’s silver, and 20% of total industrial demand. The new cells could be up to 30% cheaper than current panels. Allen developed the idea of using copper as a cheaper alternative during two years of studying for a PhD, which he scrapped to launch SunDrive. SunDrive began life in a Wollongong garage in 2015, cofounded by uni mates Vince Allen and David Hu. A startup making cheaper rooftop solar panels by replacing the silver in production with copper has raised $21 million in a Series B.
