Source: Science DailyScientists have recently discovered that diamonds, previously thought to be non-piezoelectric, can generate electricity. This breakthrough was made using ultrathin flexible diamond membranes, which showed a strong and repeatable piezoelectric effect. Piezoelectricity is the ability of certain materials to generate an electric charge in response to applied mechanical stress. This unexpected property of diamond could lead to significant advancements in various fields. The discovery suggests that diamond-powered sensors, tiny energy systems, and self-powered medical implants are now a possibility. This research challenges long-held scientific beliefs about the electrical properties of diamond and highlights its potential as a functional material beyond its traditional uses.
This discovery is important for exam aspirants as it relates to fundamental science and technology, relevant for UPSC GS Paper III (Science and Technology) and SSC General Science. It showcases a breakthrough in material science, specifically the piezoelectric effect in diamonds. Understanding such advancements is crucial for questions on new technologies, their applications, and the properties of materials. It also highlights how scientific understanding can evolve, challenging previous assumptions about common materials like diamond.

The piezoelectric effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. Conversely, these materials can also deform when an electric field is applied. This phenomenon is used in various applications, including sensors, actuators, and energy harvesting devices. Common piezoelectric materials include quartz and certain ceramics.
Diamond is an allotrope of carbon, known for its extreme hardness and high thermal conductivity. It is formed under high pressure and temperature deep within the Earth. Traditionally, diamond has been used in jewelry and industrial applications like cutting and grinding tools due to its physical properties. Its electrical properties were previously not considered piezoelectric.
Ultrathin membranes are materials engineered to be extremely thin, often at nanoscale dimensions. Their reduced thickness can lead to unique physical and chemical properties compared to bulk materials. In this context, ultrathin flexible diamond membranes were crucial for observing the piezoelectric effect, as the effect might be more pronounced or observable at such scales.
Exams often ask about new scientific discoveries, properties of materials, and their applications. Focus on the 'piezoelectric effect' and its significance, especially for UPSC GS Paper III and SSC General Science questions.
Remember 'Diamond Power' Diamonds (D) now have Power (P) due to the Piezoelectric effect.
