Quantum Dot Energy Harvesters for Powering Implantable Medical Devices
Presently, electronic medical implants such as pacemakers, defibrillators, and neurostimulators rely on batteries that require constant surgical replacement. A convenient and permanent solution will harvest the thermal energy of the human body through a simple heat engine made from quantum dots. Quantum dots are nanocrystals that exhibit special properties, namely their ability to easily morph into efficient semiconductors, which will revolutionize thermoelectric generators and supercapacitors. Heat engines made with quantum dots have high efficiencies because of their chemical potential energy, yielding high energy densities and power outputs. Our Quantum BioEngine system will generate energy through temperature gradients of the body using a solid state chip implanted subcutaneously. The convergence of quantum dot technology with biomedical devices will create a world where human power sustains human life.
