As a research project, the prototype has won a prize by “2005´s Jaime Filipe Engineer Award”
António Abreu, a Sustainable Energy Systems PhD Student under the MIT Portugal Program, currently developing research work at LNEG (Laboratório Nacional de Energia e Geologia I.P.) has developed a non-invasive battery recharger system for electronic implants that allows a longer life for the internal implantable devices in the human body such as, pacemakers, defibrillators, electric heart, delaying considerable the usual customary surgery intervention for replacement.
According to the world health organization, cardiovascular diseases are the leading cause of deaths. On a last resource, patients with cardiovascular disease have to be aided through surgery and medical devices to help them perform the basic functions. Nevertheless medical devices, such as pacemaker that sends electrical impulses to the heart muscle to maintain a suitable heart rate and rhythm, need a source of energy and once the battery has run out they required a surgical procedure similar to the initial implantation to replace the device.
With the non-invasive battery recharger for electronic cardiac implants the need for a new surgical intervention is reduced, since it primes from being rechargeable, i.e. the patient will not need to be operated upon to change batteries every five to seven years, since these are rechargeable by irradiant electricity passing through the body.
António Abreu adds that “The non-invasive battery also allows for a customize energy consumption of the cardiac implants, therefore the consumption of energy can be regulated to adapted to its function and patients’ pathology and activity. It guarantees the energetic supply of a communication channel between the exterior for diagnosis and/or implant reprogramming. In this case, there will be no demand of energy from the internal battery”.
The principle of the operation is the use of a high efficient Transcutaneous Power System. However, these typical systems use electronic converters witch generate hazard electromagnetic interferences (EMI) that causes damage to the implants as to the patients. The present innovation takes into account the Energy Efficiency in electric transmission systems without ferromagnetic cores, regarding medical application. In practice it eliminates the Gibbs phenomena.
The invention optimizes the energy flow determined by the regime of exploration previewed at the innovative Predictor-Corrector Abacus conception.
