We all know that converting the Sun's energy into useful electricity can help in the sustainable development of nations with transitional economies. But these are large scale installations. Can photovoltaic technology, which is responsible for converting the Sun's energy to electricity, be used for generating milli or even microwatts of power? This is the power typically needed for wearable and implantable electronic devices. Such devices can be used to monitor vital human signs, such as blood pressure, temperature... etc. In our group within the microelectronics lab, we have been looking into using tiny PV cells for powering implantable electronic devices.
