Energy Harvesting: Seebeck explained on a Peltier element

Captura de pantalla 2014-10-15 a la(s) 07.42.32

About the Seebeck experiment. We were fumbling around with copper and konstantan. But I had also an  idea about experimenting with a Peltier element I brought (which strangely disappearded into outer space, nowhere to be found….). We knitted the threads … Continue reading

Sound Fabric


This idea was to knit a pattern generate from a sound file (record at Paillard). This fabric will act like an antenna so when you get close to it will create a sound in correlation of the pattern you see. For … Continue reading

About a year after the workshop in Brussels…


Once upon a time there was a knitting workshop in Brussels by (Varvara Guljajeva & Mar Canet) & knitter Claire Williams: Wendy was there too…many others by the way, nice workshop atmosphere! During the workshop I couldn’t get … Continue reading

Chinese Gadets (energy harvesting)

2014-06-03 16.08.57

Some info regarding the Chinese gadgets. They are really cheap and have a few “problems”. Learning from the shortcuts used in these gadgets is fun. “Repairing” will give lot’s of experience. Some Chinese gadgets in the shop and what these … Continue reading

Energy Harvesting: former intro page


To make things more clear the former intro page is cleaned up. On this post the old text is saved. Energy harvesting is charging your e-textile circuit with power from the sun, wind, muscle, body, piezo, or even more exotic … Continue reading

Documenting Screen-Printing Circuits


This post gives some (more) visual impressions of the workshop given by Anne-Marie Lavigne and Celine Marcq on Screen-Printing Circuits. They have documented their effort already extensively here: We were all provided with a nice documentation! Information about the … Continue reading

Solar cell Efficiency (energy harvesting)


The MPPT technique is improving the efficiency of the solar cell. For solar cells you need the sun, which is in some countries somewhat hidden by clouds. Nothing to do about that. MPPT finds the voltage giving the best power … Continue reading



Finally the timelapse movie is finished. The images were shot from a fixed camera position in the big hall during eTextile Summercamp 2014 at Paillard Centre d’Art Contemporain. Thanks to Clemens Pichler there is a soundtrack too. :)     … Continue reading

MPPT (Energy Harvesting)

Captura de pantalla 2014-08-16 a la(s) 16.37.58

MPPT stands for Maximum power point tracking, although I also have read somewhere “maximum peak power tracking” for the same “MPPT”. In any energy source, be it a solar cell or a battery you have the difference of the voltage … Continue reading

Zebra Philosophy


Philosophy? Or should this be called “Zebra Critical Theory”? :-) Very impressive words… During all experimental knitting and 3D printing and trying to explain harvesting IC’s some thoughts popped up which are so easily forgotten. Still it was part of … Continue reading

Capacitor (Energy Harvesting)


A capacitor is from the energy harvesting point of view is a “sort of” battery. It can store energy, that is current at a voltage – because energy = current * voltage. A battery can produce energy, the capacitor can … Continue reading

Zebra fabrics


Group project: Zebra Fabrics. (In this post most pictures are from Beam, but he also used some pictures from the media of the summercamp blog by other participants – difficult to trace who uploaded what – , any way…many thanks!) … Continue reading

Lipo (Energy Harvesting)


Lipo or Lithium Polymer battery are not like the normal AA or AAA batteries. Unlike AA batteries at 1.5V, the lipo has a voltage of 4.1V. Decharging will make the voltage drop to 3.6V, where you should stop – normally … Continue reading

Formula’s (Energy Harvesting)


For harvesting you need a bit of calculating, otherwise you fall into the trap of confusing big and small energy. For instance: heating water is big energy, so is moving mass of kilograms. Doing a measurement with a sensor, sending … Continue reading

Voltage (Current) Regulation (Energy Harvesting)


Coming from the harvesting circuit with a diode, we encountered the problem of overcharging. If you overcharge a battery, give it more energy while being fully charged, you destroy it, or even worse (in the case of a lipo battery) … Continue reading

Diode – bridge rectifier

2014-08-12 15.00.22

The first step to make the charging circuit more reliable is to add a diode. This makes sure that the current is only flowing in the way we want it to flow, out of the energy source to the battery. … Continue reading

Most basic energy harvesting circuit

2014-08-12 14.47.39

You start with a source of energy and a way to store energy. This gives you many choices! Not all combinations of choices are good… Sources of energy can be: piezo solar cell coil and a magnet Storage can be … Continue reading

Energy Harvesting starting point


Energy Harvesting is in all its aspects quite detailed and therefore not really easy to describe in general terms. So my idea is to create this post with topics and to work out the topics individually and indicated the relations … Continue reading

Piezo (Energy Harvesting)


The Piezo element will produce electric power when it is deformed. This can happen by tapping it, (slightly) bending, pressing it. So the production is not constant in general. If you have a device which produces vibrations (eg a motor) … Continue reading
