French physicist Bruno Berge reprised research on a physical phenomena known as ‘electrowetting', discovered at the turn of the 20th century. Berge realised the potential of this phenomena in deploying the technology as a lens. His invention employs two non-mixing liquids whose interface curves when exposed to electricity, thus changing the focus of the lens. The ‘liquid lens' is now sold by the company he founded, Varioptic S.A.

TIME DESCRIPTION DURATION
00:00:00 Waiting in line at the supermarket is not fun. At least the scanning process is fast. Tiny lenses in the bar code scanners read the barcodes on the items you are buying in milliseconds. Non stop! For this work very special lenses are needed. 00:00:15
00:00:15 ... Liquid lenses! They dramatically improve the quality of even the smallest cameras, since they focus by themselves without a glass lens. 00:00:11
00:00:26 And this is all thanks to him: physicist Bruno Berge invented this tiny lens. 00:00:06
00:00:32 This ingenious idea has earned the amateur photographer from Lyon a nomination for the European Inventor Award in the category "Small and Medium Sized Enterprises". 00:00:12
00:00:44 IV Bruno Berge in French « Ma motivation était d'utiliser mon expertise dans le travail des liquides et de changement de formes des liquides pour faire de l'optique et ça rejoint ma passion pour la photographie. » Translation "I wanted to apply my experience working with liquids to optics. This also fits in with my passion for photography. " 00:00:13
00:00:57 Previously most photographic lenses consisted of several glass lenses. Turning the lens changes the distance between the lenses inside. Photographers can thus determine focal length and sharpness of a photo. 00:00:15
00:01:12 Water, oil and electricity. That's all Bruno Berge needs to make his lens. A drop of oil in water, a short electrical pulse and the droplet changes shape. Just by applying electricity, the liquid lens focuses on an object and all without any sort of mechanical effort. 00:00:21
00:01:33 IV Bruno Berge in French « L’idée d'utiliser deux liquides, elle est très simple, elle vient du fait que je voulais un système optique qui ne soit pas sensible à l'orientation. Il faut que la caméra où le système optique puisse marcher dans n'importe quelle orientation. » Tranlation “The idea of using two liquids seemed obvious and I wanted a lens that could focus by itself. The camera needs to be able to operate in any orientation.” 00:00:13
00:01:46 Berge has built his company on 45 patented inventions he owns in the field of liquid lenses. He is now the leader in this market. 00:00:10
00:01:56 IV Bruno Berge in French « Nôtres lentilles liquides, en fait remplacent des systèmes de lentilles motorisées et c'est beaucoup plus robuste puisqu'il y a aucune partie mobile. Par exemple on peut faire facilement 40 millions d'opérations là où un système mécanique va faire 100 000 opérations au maximum. » Translation “Our liquid lenses replace the system of motorized lenses. They are much more robust, because there are no moving parts. Our system can withstand 40 million releases whereas a mechanical lens is capable of 100,000 at the most.” 00:00:18
00:02:14 The liquid lenses are distinguished by their fast action and low energy consumption. Therefore they have been incorporated into many devices we use in our daily lives. 00:00:11
00:02:25 IV Bruno Berge in French « Le future est clairement vers des lentilles plus petites où plus grandes. Tous les systèmes optiques de précision en général ont des grandes lentilles. Un exemple que j'aimerais bien mentionner c'est tout ce qui est instrument ophtalmique pour aller regarder par exemple dans l'œil. ça c'est quelque chose dans lequel nous avons beaucoup d'atouts. Un autre secteur dans lequel nous souhaitons aller c'est le secteur automobile. Il y a de plus en plus de caméras dans des voitures et elles font de plus en plus de fonctions et nous avons de bons atouts pour rentrer dans ces marchés là. » Translation “The future is in either very small or very large lenses. Precision optical systems such as ophthalmological cameras have large lenses. Another area with rather small lenses is the automotive industry. There are more and more cameras in cars nowadays and they have to be particularly powerful. These are good conditions for us to break into this market.” 00:00:31
00:02:56 Now Berge’s focus is on the 28th of May in Amsterdam. That's when and where we will see if the tiny liquid lens earns its creator the "Technology Oscar" at the European Patent Office's Inventor Awards. 00:00:18
00:03:14 The competition is tough, but Bruno Berge has much going for him: He's the one who has given us much more transparency. 00:00:09
