Instead of switching off the power, they could run the voltage up and down to wreck sensitive electronic equipment, such as computers and television sets.
The generator achieves maximum OCV (open-circuit voltage) up to 2.25 V and CCV (closed-circuit voltage) up to 1.55 V which is 0.276 μW per centimeter square.
However, the antennas require high voltage (up to several thousand volts), which will bring electrostatic damage and safety risks to electronic products on the spacecraft.
Temperature can rise up to 200 °C and a voltage up to 2000 V can develop between shell and vessel during machine operation.
A glow discharge occurs when a DC voltage (up to 3 kV) is applied between two electrodes in a cell filled with Ar at ∼1 hPa pressure.
The ASIC implements a single photon avalanche diode detector (SPAD), and integrated high voltage (up to 37.9 V) charge pump power supply.
One individual harvester achieves a maximum OCV (open-circuit voltage) up to 4 V with power density of 1.247 μW/cm3.
The gas pressure was 0.01 600 Pa and a negative pulse, DC, RF, and RF+DC voltage (up to −20 kV) was applied to the target.
They use high voltage (up to 1000 V impulses) and low frequency (25 50 MHz antennae), which can reach up to 40 m depth in low conductivity ground conditions.
For future works, we recommend to do some additional measurements with a higher voltage (up to 200 kV in laboratory and more in substations) and extend the focus around ISM bands to other wireless technologies like ZigBee, Wimax, or LTE.
The integrated intensities of PL, EL and EPL, together with the calculated SUM (EL + PL) and gain are plotted in Figure 12, as function of applied voltage, up to 800 V/cm, with laser excitation power of 10 mW.
