It’s hard For Brazilian blood banks to maintain their stock levels. To help them achieve this, we came up with a strategy to make the issue part of people’s everyday lives and attract donors on a more regular basis. Instead of a campaign, we launched a gadget that uses the same principle behind blood donations. We developed a cable which ‘transfuses’ energy between smartphones. You just need to connect a donor phone with a full battery charge to bring life to a powerless one.

The product began to attract attention at trial points. Places like the Outback Steakhouse restaurant chain, which attends about 41,000 people per day in Brazil. After just a short period of time, photos, videos and posts about the gadget spread across the internet, drawing the attention of a number of wide-ranging media channels. A simple cable became the best conductor of an unexpected and essential message.

We created a gadget that uses the same principle behind blood donations. The accessory is part of an existing technology, but applied in a different way. It is based upon cables which connect smartphones to laptops. In addition to a different input, we put the device into an Arduino electrical circuit to accelerate the energy transfer process.

The new gadget was used in trials at the Outback Steakhouse restaurant chain, our first partner. Every time someone made an energy transfusion, they were told how they could donate blood at the nearest blood bank.

The product began to attract attention at trial points in the restaurants. Around 41 thousand people go to Outback steakhouses every day in Brazil. After just a short period of time, photos, videos and posts about the gadget spread across the internet, drawing the attention of a wide range of media channels. A simple cable became the talking point of many articles on both health and technology. Wider media coverage, in addition to increasing awareness and generating greater demand for the new product. So much so that a large chain store has already showed interest in producing it on a large scale - with a percentage of profits going towards equipping blood banks in Sao Paulo, of course.
