Block diagram of an energy harvesting system using a piezoelectric transducer. Fig. 2 shows a block diagram of an energy harvesting system that can power a pacemaker.

The solar measurement device block diagram shown in Fig. 2 employs a memory card to store the voltage/current values along with date and time.

Figure 1 shows a block diagram for a power supply like TDK-Lambda’s CUS350M, which features a main output, an auxiliary output (typically used for driving fans) and a standby voltage.A remote on/off ...
