Piezoelectric Effect in Liquids

Context: Piezoelectric effect has been reported for the first time in liquids.

More on the News

  • The effect has been observed in ionic fluids pure 1-butyl-3-methyl imidazolium bis (trifluoromethyl-sulfonyl) imide and 1-hexyl-3-methyl imidazolium bis (trifluoromethylsulfonyl) imide.
    • Ionioc liquids are made of ions instead of molecules.

What is Piezoelectric Effect?

  • In piezoelectric effect, a body develops an electric current when mechanical stress is applied. Till now, this phenomenon has been observed only in solids, especially crystals such as quartz.
  • Occurrence: When a mechanical stress is applied, a shifting of the positive and negative charge centers in the material takes place, resulting in an external electrical field.
    • The body undergoing mechanical stress needs to have an organized structure, like the pyramids of quartz. Liquid usually takes shape of the container and hence cannot experience piezoelectric effect.

  • Unique feature: One unique feature is that piezoelectric effect is reversible, meaning that materials showing the direct piezoelectric effect also display the converse piezoelectric effect (the generation of stress when an electric field is applied).
  • Potential applications of new research
    • Ionic liquids are more readily recyclable and pose fewer environmental issues compared to existing piezoelectric materials used.
    • Using their converse piezoelectric characteristics, these ionic liquids can be used in simple control mechanism by converting them into lenses with dynamic focusing abilities.
  • Challenges ahead
    • There is a need to develop a theoretical framework with predictive power to understand the experimental observations in ionic liquid and develop it further.

National Policy for Rare Diseases, 2021


Food and drugs to be used for treatment of rare diseases under the National Policy for Rare Diseases, 2021 will be exempted from basic customs duty.

What are Rare Diseases?

  • Rare disease is a life-threatening condition that affects a small number of people compared with other existing diseases.
  • Different countries have different definition. India classifies the disease as rare if the prevalence rate in population is 6% to 8%.
  • Status: Currently, there are about 6000 to 8000 rare diseases. However, 80% of all patients are affected by approximately 350 rare diseases.
    • About 95% rare diseases do not have approved treatment and less than 1 in 10 patients receive disease-specific treatment.
    • About 80% of rare diseases are genetic in origin and hence disproportionately impact children.
    • In India, 72 to 96 million people are affected by rare diseases. Most of the patients do not reach adulthood due to the high mortality. 
  • Effects of rare diseases
    • Affects younger population: Rare diseases are responsible for 35% of deaths before the age of 1 year, 10% between the ages of 1 and 5 years and 12% between 5 and 15 years.
    • Financial cost: The cost of treating rare diseases is very high, having a catastrophic effect on finances of families.

National Policy for Rare Diseases, 2021: Highlights

  • Categorizing rare diseases:
    • Group 1: Disorders treatable through one-time curative treatment.
    • Group 2: Need long term or lifelong treatment.
    • Group 3: Definitive treatment is available but challenges occur in form of very high cost and lifelong therapy.
  • Funding
    • Individuals suffering from rare diseases listed under Group 1 will be provided financial support of up to Rs. 20 lakh.
  • The benefits will be extended to 40% of the population, who are eligible under Pradhan Mantri Jan Arogya Yojana.
    • It also allows voluntary crowd funding treatment by setting up a digital platform.
  • Registry of rare diseases: A registry of rare diseases will be created to ensure adequate data for those interested in research and development.
  • Treatment centres:
    • There are plans to set up eight ‘Centres of Excellence’ at designated places for prevention and treatment of rare diseases.
    • They will be provided one-time grant of up to Rs. 5 crore for upgradation of diagnostics facilities.

Orphan Drugs

  • Orphan drugs are a category of medicines that are used to treat rare diseases. Since the prevalence of a rare disease is low, the production of orphan drug would not be profitable.
