Interactive Light Panels (2010 – 2014), Benjamin Piltz


The Creator

Benjamin Piltz is artist engineer. He combines his capabilities as engineer to solve technically advanced solutions with the gift of an artist to to give his self into his work.

Born 1977 in Frankfurt am Main, grown up in Baden Würthemberg, Germany, he got in touch in his youth with art and creative work of many kinds.

His career began after finishing at a technical grammar school and the following studies at a advanced technical college in the field of study of electronics and communications engineering. He joined the company Lawo AG in Rastatt, leading manufacturer of broadcast and networking audio equipment where he build up quality management in the companies own production division. By developing and adapting testing systems and supporting new product ramp ups he gathered much experience. A continuous dialogue between other divisions like development and research as well as with suppliers also contributed to a huge knowledge base which formed the fundament for the latest creations.

These are a bunch of prototypes and studies as well as three generations of interactive lighting panels. The electrical circuits as well as the according software are all own designs.

Those interactive light-devices are protected as utility model at the German Patent and Trademark Office.

The company Sensavo Technologies ( is the development and production facility of the interactive lighting technology. After a certain degree of complexity of an design it is necessary to use a company. Otherwise it would not be possible to get certain electronic components for example. Sensavo also serves as a platform to instantiate special projects for events and architecture which come up to light and/or interactivity.



The Creation

The interactive light panels of Benjamin Piltz / Sensavo work with a conjunction of multiple sensors and coloured LEDs. Capacitive sensors in the surface of the panels recognise the electrical field change of the surrounding. As the resolution of the measurements is very fine the surface is very sensitive and either touch or even approximation in the near field can be recognised. The measurements are then processed and translated into colours which are then displayed again in the surface.

One emphasis all of the panel generations have in common: Showing a certain way of naturalness and liveliness within the objects. The mechanical squarish forms of the hardware stands in opposition to the soft and fluid, radial emitted light. This conjunction is an allusion to the character of body and spirit. Thereby the physical form stands for matter and the fluid light for spirit. The conjunction with oneness is pronounced additionally with the sampled noise floor captured by the sensors when nobody is near to the surface. Then the natural fluctualtions of the electrical field influence the images processed. The result is organic movement for example like plasma showing an certain order within themselves. In this way the objects open up a channel for the living and the natural that always tends to express it’s self.

When the visitor gets in touch with the objects he connects to the outer mater but also to the internal natural alive and to the cosmos over the background noise of the field. The experience of actually creating light with the body for example a trace of light, causes a deep resonance within the interacting human.  This is because light plays an essential role within the body. The pixel are arranged in a matrix array and are connected through software and the electrical field – just like the cells of a living organism.

Meanwhile the third generation (flux03) of the interactive light panels is finished. Driven by the technical ambition of a true engineer the development of the idea was taken that far, that now the integration of the panels into greater total works of art is possible. This is because interfaces open up the possibility to display external contents and to be controlled over common interface standards. This version can be used as a floor smoothly. In this way it is possible to integrate them into dances/theatres/shows. For the third generation there is no limitation planned so far. The first two generations will not be manufactured any more and are therefore very limited:



2x SX32

SX32 (2010)

manufactured 4 x

6x flux02 DLD 2012 green

6x flux02

flux02 (2011)

manufactured 8 x

4 x flux03 Installation

4 x flux03 installation

flux03 (2014)

manufactured 5 x, further 25 pcs. are planned



At this time a concept for a touring exhibition is being prepared together with the Israeli artist Shachar Pessis. The theme shall be “peace”. We think of doing an installation with the flux03 system configured in different ways. The outer form will have different shapes tying up to the “peace” theme. For example by forming a bridge where people can walk over and interact with it. “Recognise yourself” by touching the objects may also be a part of the installation.

Some ideas about financing the whole thing have been done so far: For example single interactive pixels could be made as a “thank-you” gift for a prior donation or could be sold also. Some limited amount of options on single objects featuring price benefits for a buy after the exhibition is finshed may be a possibility or sponsored exhibitions could also be done. The elements of the touring exhibition will form a limited edition which shall be sold afterwards in cooperation with galleries.


Also there will be more single and unique objects in the near future working with a conjunction of light, object and a sensitivity to external influences in order to create something natural responding, alive. The first of these objects are being created right now.
