Professor Kofi Makinwa is Antoni van Leeuwenhoek Professor in the EEMCS Faculty, specialising in smart sensor systems. He arrived at TU Delft from the Philips Research Lab to do doctoral research in 1999. The aim was to develop a wind meter (or anemometer) with no moving parts. "It's like sticking your finger in the air. A warm object cools asymmetrically in the wind. Our aim was to derive the wind direction and speed from the temperature profile," he recalls. He made three prototypes with heating elements, temperature sensors and various quantities of electronics on the chip. The idea was to balance cooling with additional heat. The power needed to achieve that could be used to derive the wind force and direction.
