How to apply

When designing compact scientific instruments for resource-constrained environments (e.g., remote sensing, portable devices), prioritize low-power components and consider custom circuit design for critical functions.

Project actions

01When designing a sensor, think about how much power it will use. Can you use smaller, more efficient parts?
02Consider if you can build custom parts of your design to make it work better or use less energy.

Method & Evidence

AimTo design and evaluate a power-efficient Terahertz (THz) radiometer payload for detecting water on Mars, and to develop an optimized trajectory for a Mars exploration mission.

MethodExperimental and Algorithmic Design

ProcedureA THz payload was constructed using a subharmonic Schottky diode mixer and a tripler circuit, both employing Schottky diodes. Custom DIY spectrum meter and signal generator circuits were developed to support the mixer and tripler, respectively. The power consumption of the complete payload was measured. Separately, a dual-step hybrid optimization algorithm (PSO-Homotopy) was used to analyze fuel-efficient low-thrust trajectories from Earth to Mars, considering ephemeris dynamics.
