This project explores piezoelectric and thermoelectric technologies to design a self-sustaining mobile power bank that harnesses wasted thermal and kinetic energy.
To provide a clean energy source without interfering with phone usage, the power bank should be placed on the back of the smartphone rather than the screen.
First,
Spacecraft electronics are vulnerable to damage from temperature extremes, impacts, and long missions. Traditional PCBs cannot repair themselves after cracks or fractures, risking total mission failure.
This invention introduces self-healing PCB circuits using embedded microfluid channels underneath the electrical traces. If a trace fractures, conductive liquid metal flows into the break and restores the circuit automatically.
The design life of a wind turbine is twenty years. Considering the significant growth in the number of wind turbine installations since the 1990s, it can be concluded that many of these installations have already reached their applicable life limit or are on the verge of exceeding it.
Market penetration of Battery Electric Vehicles is still very low (~3 to 4% in India, ~ 8% in the US). Factors responsible include resistance arising from a fear of unavailability of charging stations in long trips or charging station not working properly. Also, charging grid electricity is most often obtained from coal and fossil fuel plants,
INTRODUCTION
The Sensor-Controlled Gravity/Buoyancy Power Pit Generator is an innovative renewable energy system designed to operate efficiently in any geographic location, overcoming the limitations of conventional renewable sources such as solar, wind, and hydroelectric power, which are highly dependent on specific weather conditions. Unlike these traditional systems,
Sensorix Foot () is an innovative medical device that integrates continuous thermal monitoring and targeted vibration therapy into an intelligent sandal designed to protect and improve foot health in individuals at risk of vascular, neurological, and inflammatory conditions.
What problem does your design idea solve?
On the modern battlefield, a critical dilemma exists: to see, one must emit energy with active radar, which instantly reveals one's position to be jammed or targeted. This makes surveillance a high-stakes gamble. Furthermore, the proliferation of stealth technology has rendered many conventional radar systems obsolete,
Oblique Wing research-driven design addresses the aerodynamic inefficiencies of conventional symmetric wing configurations at high-speed flight regimes by proposing a structurally optimized oblique wing (OW) configuration. Unlike conventional sweep-back designs, the OW incorporates a single-pivot, asymmetric wing structure capable of variable sweep adjustment,
Magnetic reconnection converter (MRC) based on a single-volume plasma (spheromak) with a variable β in the turbulent pumping (charging)/discharging phases of the thermodynamic duty cycle “α-dynamo – magnetic reconnection”. To obtain helpful energy, the proposed MRC uses a cyclic combination of two physical processes:
α-dynamo, generated by controlled turbulence,
