Abstract
In this paper, a wireless temperature measurement system powered by energy harvesting from human motion is presented. The user force exerted on the hand-crank ElectroMagnetic (EM) device is converted into electricity. The electrical energy is stored into multiple capacitors by the proposed active power management circuit with the Sequential Charging of the Storage Capacitors network (SCSC). With an applied force of about 29.4 N over 2 cm, 27.5 mJ of energy are stored and used to power the wireless temperature sensor module. The module performs a noncontact temperature measurement, shows the reading on an LCD display, and sends the temperature data over a wireless-UART link at 433 MHz to a host PC.
