  • 2014

    Starting in February 2014, the project was born from the dream of bringing together the scientific world to the industry. The ability to apply the skills and innovative technologies that are being developed by researchers with extensive experience was a must. With the participation in iUP25K, the i.nanoEnergy project began. The idea took us to the finals of this business idea competition, but this didn’t stop us. With the formulation of the idea and the business plan, the project was awarded two grants from IAPMEI entrepreneurship allowing the founders to start a technological development. Since then many advances have been made in the development of the first prototypes, creating partnerships and exposure of the project. Within one year of existence, i.nanoEnergy was already a finalist in two entrepreneurship contests, the iUP25k and IDEup, obtained two grants to support entrepreneurship, made several scientific presentations at international conferences (ANM 2014 and EDNANO 2014) and developed the first functional prototypes already with an applicable possibility.


    In 2015 i.nanoEnergy participated in the UPTEC School of Startups (April to September), which allowed us to learn more about management, finance and pitch techniques, and opened the doors to new investors and partnerships. In May 2015 we also participated in the ClimateLaunchpad, the Europe’s largest cleantech business idea competition, in which we reached the national finals. Finally, in December 2015 we created the Startup InanoEnergy – Consulting, Design, Production and Application of Renewable Energy Solutions Ltd., and incubated in UPTEC. Since December 2015 we participate in the European Space Agency Business Incubation Centre Portugal, which will last until December 2017.


    During the first year of incubation at UPTEC and participation in the ESA BIC Portugal program, i.nanoEnergy developed two prototypes of micro-/nano-generators. One uses the hybridization of two different technologies to generate electricity while walking. The other uses a new technology with an innovative design (patent application in process) that allows the generation of energy with the movement of water. In addition to the development of prototypes, in 2016 i.nanoEnergy participated in the “Mentes que Brilham” program of Porto Canal, made several radio interviews and attended several events related to Energy and the Internet of Things (IoT), such as Green Bussiness Week, Startupbootcamp Smart Transportation & Energy, Microsoft IoT Summit, UPTEC Non-Stop – Product Showroom, ESA Couture in Orbit and 2nd Anniversary of ESA BIC Portugal. i.nanoEnergy was also one of the semi-finalists of the Acredita Portugal entrepreneurship competition, hosted two trainees from the Erasmus+ program, and attracted Repsol’s interest in the development of micro-generators in extreme conditions.


    During the second year of incubation at UPTEC and participation in the ESA BIC Portugal program, i.nanoEnergy continued to develop prototypes of micro-/nano-generators. The most relevant include: i) a triboelectric sensor to be placed on the insole of a shoe and measure the pressure distribution exerted at the bottom of the foot while walking; ii) an energy generator that uses new technology with an innovative design (approved patent number WO 2017/158513 A1) to generate energy with the movement of a fluid. This last product attracted the interest of the company Águas do Porto, with which i.nanoEnergy began to work. In 2017, i.nanoEnergy also contacted several other companies, such as Autoeuropa, Fundación Repsol, InoDev and Efacec, participated in several events related to Energy and the Internet of Things (IoT), such as Cidade+, 1st KIC InnoEnergy Reverse Pitch, Porto Water Innovation Week, Workshop on Emerging Technologies for Energy and Training Workshops of the 6th Call of the Repsol Foundation Entrepreneurs Fund, made several interviews for the radio and participated in dissemination videos (inanoE – ESA BIC Portugal). In 2017, i.nanoEnergy also became a spin-off of the University of Porto, won a European project H2020 (739797 – HarshEnergy) with which it hired a doctoral researcher, was one of the 4 ideas selected in the 6th Call of the Entrepreneurs Fund of the Repsol Foundation, among the 354 proposals received from more than 20 countries, and was also the winner of the 3rd prize of the Splash Innovation Stage competition and the innoEnergy special prize of the same competition, which awarded the startup with the highest potential in terms of energy efficiency. At the end of 2017 i.nanoEnergy became one of the startups incubated at the Repsol Foundation, developing micro-generators to power small sensors/batteries in remote places and extreme conditions.
