Technological advancements and groundbreaking inventions from the late 20th and early 21st centuries have fundamentally transformed computers, electronics, manufacturing, and daily life, propelling us into a new era of innovation.
While nations like the U.S., China, and Japan are renowned for their technological prowess, India has also made indispensable contributions, addressing critical global tech needs. This article highlights seven pivotal tech inventions and discoveries that originated from India.
Universal Serial Bus (USB) and USB Port
For the seamless transfer of files between computers and portable devices, and the effortless connection of various peripherals, modern technology users can largely thank the Universal Serial Bus (USB). This ubiquitous technology was co-invented by Ajay V. Bhatt, an Indian-born American computer architect from Bengaluru.
Ajay V. Bhatt pioneered the development of the USB in 1995, driven by the critical need for a standardized port compatible across diverse computing platforms. This innovative concept and its widespread adoption empowered manufacturers of peripheral devices such as keyboards, speakers, and mice to streamline their designs. The result was significantly reduced production costs, enhanced overall compatibility, and a more user-friendly experience for consumers worldwide.
Beyond his revolutionary work on the USB, Bhatt also played a crucial role in advancing other vital technologies, including the Accelerated Graphics Port (AGP), PCI Express, and Platform Power Management Architecture, alongside numerous other chipset enhancements. His contributions have undeniably shaped the landscape of modern computing.
Simputer: India’s Vision for Affordable Computing
The Simputer, launched in 2002, was an innovative, self-contained, open hardware, Linux-based handheld computer. Developed and primarily distributed in India, this device was conceived as a cost-effective alternative to traditional personal computers, aiming to bridge the digital divide.
The Simputer Trust, a non-profit organization established in November 1999, spearheaded the device’s design. This trust comprised seven distinguished Indian scientists and engineers, with Dr. Swami Manohar at the helm. The name “Simputer” is an acronym, standing for “simple, inexpensive and multilingual people’s computer,” reflecting its core mission.
Equipped with text-to-speech software, the Simputer ran on the Linux operating system. Its appearance resembled that of the PalmPilot class of handheld computers, featuring a touch-sensitive screen operated with a stylus. The device also incorporated basic handwriting recognition software, facilitated by a program called Tapatap.
Despite ambitious initial sales targets of 50,000 units, the Simputer project sold approximately 4,000 units by 2005. Consequently, several news outlets characterized the project as a commercial setback.
Pioneering Fiber Optics Technology
Optical fibers are lauded for their ability to deliver undisturbed, high-speed data transmission. These advanced fibers are primarily utilized to transmit light between two ends, facilitating clear and expansive communication across various networks.
While French scientists Daniel Colladon and Jacques Babinet initially demonstrated the underlying principles, it was Indian scientist, entrepreneur, and philanthropist Narinder Singh Kapany who introduced the term “Fiber Optics” and published the first comprehensive article on its engineering applications and uses to the world.
Born in Punjab and a graduate of Agra University, Narinder Singh Kapany is widely celebrated as the “Father of Fiber Optics.” His pioneering journal articles and books were the first to extensively detail the field. He coined and elucidated the term “fiber optics” in a 1960 issue of Scientific American and subsequently founded Optics Technology Inc., cementing his legacy in optical communication.
The next time you appreciate your stable fiber-optic internet connection at home or work, remember to acknowledge Narinder Singh Kapany, one of the 20th century’s unsung technological heroes.

Jagadish Chandra Bose: Pioneering Radio Waves & Microwave Communication
While the advent of video transformed media, radio waves continued to evolve, finding diverse applications from telecommunications to broadcasting signals. The late 19th century saw extensive research into radio waves and microwave communications.
However, it was Jagadish Chandra Bose’s groundbreaking experiment in 1895 that truly illuminated the profound potential of microwaves for communication.
Using his custom-built apparatus, Bose successfully transmitted microwaves, demonstrating their nature as an “invisible light” capable of effortlessly penetrating solid objects.
Bose’s revolutionary demonstration laid the essential groundwork for numerous modern technologies. His work is fundamental to mobile telephony, radar systems, satellite communications, radio, television broadcasting, Wi-Fi, remote controls, and countless other ubiquitous applications we rely on daily.
The Revolutionary Pentium Chip
The introduction of the Pentium microprocessor chips marked a significant leap in computer processing capabilities. Microprocessors, like those powering your personal computer or smartphone, contain millions of transistors designed to execute numerous functions in mere milliseconds.
The credit for this pivotal chip goes to Vinod Dham. Widely recognized as the “Father of the Pentium Chip,” Dham developed this groundbreaking processor for Intel in 1993. Upon its release, the Pentium chip surpassed its contemporaries, including microprocessors from Motorola, SPARC, and Alpha, establishing a new performance benchmark.
The Pentium’s innovative superscalar architecture and 64-bit computing capabilities continue to form the fundamental technological basis for many modern computer chips, highlighting its enduring impact.
Hotmail: Pioneering Webmail Service
Many Windows users globally rely on Outlook for their email needs, a service that traces its origins back to Hotmail. Hotmail was one of the internet’s earliest webmail services, co-founded by two visionaries, including Indian entrepreneur Sabeer Bhatia. On July 4, 1996, Sabeer Bhatia, alongside his colleague Jack Smith, launched hotmail.com. This pioneering service was later acquired by Microsoft in 1997 and eventually evolved into Outlook, significantly impacting the landscape of online communication.
Digital Vaccines: Promoting Healthy Habits
How can we encourage children to choose healthier foods over sugary drinks and junk food? An innovative Indian startup is addressing this challenge by utilizing “Digital Vaccines” to promote healthy eating habits in a fun and interactive way.
Technology and innovation are crucial for enhancing processes and experiences across all sectors, including the vital area of fostering positive behavioral changes in children.
FriendsLearn, a Chennai-based company founded in 2011, has successfully completed trials demonstrating “path-breaking evidence” of its ability to positively influence children’s food choices. This is achieved through an engaging mobile game rooted in neurocognitive science and virtual-reality stimulation-based implicit learning.
