Tica Lab - electrified mosquito net

Openhardware electrified mosquito net to fight malaria (paludism)

Similar projects worth following
Malaria is the most frequently occurring and serious vector-borne infection among parasitic illnesses. Each year, this ever-growing disease is responsible for more than 400 000 deaths.
Insecticide-treated nets are one of the multiple solutions that have been developed over the years to fight against Malaria.
However, mosquitos are developing a resistance against these chemicals.

Tica-Lab is a mosquito net that uses a capacitive technology to electrocute mosquitoes when they land on the net. The product is also able to distinguish a human from a mosquito, therefore avoiding any unwanted shocks for humans.

We are working together with universities, NGOs and companies to garner expert feedback and understand how the local needs can be met in the most effective way possible.

We are a unified non-profit organisation, and our project is openhardware/opensource.

If you want to take part in our fight against Malaria, make sure to contact us and follow the project!

The mosquito net is made of aluminium yarns and aramid yarns (Kevlar)

  • Meeting a french weaver

    Mattis EYNARD10/05/2021 at 13:01 0 comments

    Last week Jeanne and Mattis met with a French weaver in order to generate technical solutions to create and produce a bigger prototype.

    They had the opportunity to learn the intricacies of weaving works during a fascinatingly educational visit of the facilities.

    This knowledge is truly enlightening and useful for our project; knowing the industrial requirements will lead us to create a more practical design that will  be easier to produce, and more cost-effective with regard to production.

  • 4S innovation contest

    4S Innovation is a contest, created by the French bank “Le credit Mutuel” in order to promote innovation in the young generation.

    We had the chance to take part in this contest and to participate to numerous workshops that helped us improve the project. The final round was yesterday, and we are one of the four winners!

    This means we won 4000€, along with a coaching provided by the Credit Mutuel in order to help us enhance our project. This is an awesome help to the project and we are really thankful to the Credit Mutuel for it!

  • Global Industrie at Lyon: looking for a manufacturer

    Mattis EYNARD09/08/2021 at 07:41 0 comments

    We were yesterday at the “Global Industry” exhibition in Lyon to meet different manufacturers.

    We have already developed a small prototype of the net (which was made in China), and we are now looking for a company that can make larger nets to prototype the whole mosquito net.

    We finally found someone who said to be able to make it so we will keep you updated about this!

  • Test at Pasteur Institute

    Mattis EYNARD08/24/2021 at 07:58 0 comments

    During July, we had the opportunity to test our net directly on mosquitoes at the Paster institute in Paris.

    Our aim was to find the most effective voltage and current to electrocute them.

    For this, we made a Plexiglas box, with a window closed by our electrified net. We applied different voltage-current pairs to see which suited best our application. After drawing the survivor curves we were able to analyse the efficiency of our net. Further researches will be published in a little article soon.

  • Measuring capacitance with ESP32 board

    Mattis EYNARD07/08/2021 at 10:32 1 comment

    To measure the capacitance of a capacitor, we have decided to make a RC circuit (resistor – capacitor): first, we charge the capacitor, then, it discharges itself in the resistor.

    We take (you can change the values, it depends in fact of the range that you want, mine is for capacitors around 1µF)

    R = 1k = 103 ohm

    t =  10-3 s

    V0 = Vcc = 3.3V, corresponding at 4095 when read with AnalogRead() on Esp32, or 1023 on Arduino uno


    It works!

    I have left the loop running 24 791 times, and calculate the average and the standard deviation with Excel.

    We find 935,7 nF, with a standard deviation of 2.99, which is quite good!  

    Using my multimeter, I find 962.5nF. The difference is probably due to the internal resistance and capacitance of the ESP32 board.      

    We have used an esp32 devboard as microcontroller, but you can use an Arduino board. The code would be the same.

    Be careful: Arduino uno has a 10-bit ADC (analogic digital converter), ESP32 a 12-bit ADC: so the values returned by Arduino would be comprised between 0 and 1023 (210 values) and ESP32 between 0 and 4095 (212 values).

    Use in our mosquito net :  

    Our net is a sort of capacitor, the human body is a capacitor too. In fact, any material behaves as a capacitor. When a human approaches, the capacitance of the global system is modified. We can detect this variation in order to stop applying electric shocks.

    We don’t need to really calculate the capacity, we will only analyze the voltage of the capacitor (using the same circuit), because the voltage after a time t is related to the capacitance.

    Avoiding complicated calculations permits to limit the use of energy and time resources.

  • Test at Centrale Lyon

    Mattis EYNARD07/07/2021 at 17:20 0 comments

    At Centrale, an engineering school, we wanted to see if we can detect when the human body approaches the net.

    For that, we used an impedance meter. We have clearly seen that this technology could work for this application.

    Now, we have to make a system which measure the impedance and an algorithm which interpret if a human approaches or not.

don't you the fear to be electrocuted? last year i used regular nets on all the windows and doors. no insects in sight.

  Are you sure? yes | no

Mattis EYNARD wrote 04/14/2021 at 07:05 point

Thank you for your comment!

We are developping systems to limit current, so there is no risk!

Regular nets work, but are not totally proof, so isn't sufficient to fight against malaria.

  Are you sure? yes | no
