Implantable mechanical devices

-
Image
Within 20 years, implantable devices will increasingly incorporate electronics to enable noninvasive assessment. Current cardiac stents simply revascularize arteries; future stents may include sensors that use radio-frequency identification (RFID) to report vessel status wirelessly when scanned over the chest. Sensorized artificial discs will be implanted in the hip, spine, or knee to noninvasively monitor load and verify proper function, as shown in Figure 2. If excessive load or malfunction is detected, the sensors will alert the patient and caregivers so corrective measures can be taken promptly. High-performance sensors have not been widely used in implants because proteins and the immune system can attack devices, limiting long-term efficacy. Over the next 20 years, cellular biology approaches will reduce immune recognition of sensors as foreign bodies. Biocompatible materials will be essential for all implantable devices.

                                                                           ADVANCED FOOTSTEP POWER GENERATION SYSTEM      An Advanced Footstep Power Generation System is a renewable-energy system that converts the mechanical energy produced when a person walks into electrical energy . It is suitable for places with heavy pedestrian movement such as railway stations, bus stands, shopping malls, colleges, hospitals, airports and public walkways. The rapid increase in energy demand and depletion of conventional resources has created an urgent need for alternative and renewable energy solutions. Among various innovative approaches, energy harvesting from human motion has emerged as a promising technique. The Advanced Footstep Power Generation System is a smart renewable energy concept th...

Drones in agriculture

-

  Drones in agriculture Drones in agriculture are used to enhance and optimize various farming activities such as crop monitoring, crop spraying, soil analysis, and mapping. In fact, agriculture is one of the major sectors to incorporate drones. Drones equipped with sensors and cameras are used for imaging, mapping, and surveying farms. There are ground-based drones and aerial drones. Ground drones are bots that survey the fields on wheels. Aerial drones, formally known as unmanned aerial vehicles (UAVs) or unmanned aircraft systems (UAS), are flying robots. Drones can be controlled remotely or they can fly automatically through software-controlled flight plans in their embedded systems, working in coordination with sensors and GPS. From the drone data, insights can be drawn regarding crop health, irrigation, spraying, planting, soil and field, plant counting, yield prediction, and much more. Drones can either be scheduled for farm surveys (drone as a service) or can be bought and ...

Hydrogen fuel cell cars pros and cons

-
Image
  Hydrogen fuel cell cars pros and cons Pros of Hydrogen Cars Zero Emissions: The only byproduct emitted from the tailpipe is water vapor. Fast Refueling: Refueling a hydrogen tank takes only 3 to 5 minutes, offering the same convenience as traditional gas cars. Long Driving Range: A single tank provides a range of about 300 to 400 miles, making long-distance travel easy. Weather Resilience: Hydrogen fuel cells handle extreme cold and hot weather better than standard lithium-ion batteries, losing less overall range.   Cons of Hydrogen Cars Low Energy Efficiency: Converting electricity to hydrogen and back to electricity in a fuel cell loses a lot of energy; hydrogen cars use only about 30% to 35% of the input energy, compared to 80% for battery electric cars.   Lack of Infrastructure: There is a severe shortage of public hydrogen refueling stations outside of very limited areas (like parts of California).   High Cost: The vehicles themselves are expensiv...
