Doorsteptutor material for CLAT is prepared by world's top subject experts: fully solved questions with step-by-step explanation- practice your way to success.

First time wireless transmission of electrical energy has been achieved. Key components-nanowires. Nanogenerator-A small electronic chip that harvests mechanical energy and converts it into electrical energy.

Triboelectric Effect- A Type of Contact Electrification


  • Can be used to light up homes, control doors and even set burglar alarms.
  • Can be installed at airports, sidewalks and battery.
  • Can be placed on the nearby walls to store the energy.
  • Using an actuated remote, electric field can also be made.
  • E. g. Tapping the W-TENG and using its electric field as a button to open a door or activate a security system, all without a battery.
  • No wires involved.
  • No need of power outlets.

The wireless feature extends its application

  • Resource-limited settings.
  • In outer space.
  • In middle of the ocean.

MediPix Technology

  • Use of accelerated particles.
  • Production of first three-dimensional colour images of the human body.

Concerns with Traditional Radiological Practices

  • X -Ray Techniques.
  • Magnetic resonance imaging (MRI) .
  • Positron emission tomography (PET) .

Significance of MediPix Technology

  • Use of Medipix to image cancerous tissue, bones and joints and the blood supply to the heart.
  • Depict structures exactly as they are.
  • Using algorithms to model very accurate spectroscopic data in three dimensions.
  • This technology is expected to make a difference to the efficacy of care.
  • For fracture related cases, it shows physical damage to a bone.
