LED Mosquito project

If you like what you see, don't just copy our technology, join SENSORICA. It is in your best interest! Here's why


The LED Mosquito project aims to design and commercialize an open source, low cost Mosquito sensor. This Mosquito uses an LED light source instead of a laser (LD) source.

Mosquito hardware manual


The LED Mosquito sensor is a low-cost displacement and force sensor. It can be used as a scientific instrument in biology and physiology, to study mechanical properties of tissues. Unlike the laser Mosquito, the LED Mosquito is less sensitive and cannot be applied at the cellular and sub-cellular level. Another application is in education - see Mosquito educational system.

  • PMMA fiber joint-type transducer for LED Mosquito Christopher is now working on a new Joint-type transducer for PMMA fiber to be used with a low cost LED-based Mosquito.

  • LED Mosquito in the visible A new LED Mosquito is being built with very low cost parts.

  • New LED 850nm Mosquito is in a box The new LED 850nm Mosquito goes in a box. This is the Prototype II (open document to see more).We are now using it to produce different types of transducers optimized for this new device:125/62.5 MM Corning glass fiber joint-type (flat tip and round tip)constriction100um MM glass fiberjoint-type (flat tip and round tip)constriction250um PMMA fiberconstrictionThis Mosquito will then go to Phil's lab, and we'll build another one for our lab. After a few weeks of testing think of building a demo prototype to take it on the road (see Path to market).

  • LED-based Mosquito turns out to be more stable The making of the prototypeOn April 02, 2013, Tibi, Jonathan and Daniel had a "Mosquito Sprint" to assemble and test a new Mosquito using an LED at 850nm and a photodiode with a TIA (transimpedance amplifier) integrated. The experiment was done on a breadboard, no new Mosquito prototype was made.The optical design used depicted in the diagram below and described HERE. We measured the signal through a Y coupler/splitter coming from the force transducer [sensing application]. The signal is still small, because of poor optical coupling between the LED and the MM glass fiber. We tried different LED's, but the one that worked best is a high power and has 4 wires on the semiconductor (normal ...
