How Siddarth Nandyala’s STEM Innovations Bring Second Chances
From a chance meeting in India to global impact, Siddarth Nandyala is inventing a better future.
Have you ever met someone limited in life because they couldn’t afford something essential? During a family trip to India, thirteen-year-old Siddarth Nandyala met a boy about his age who was missing an arm. The boy’s family couldn’t afford an expensive prosthetic. This seemed so unfair to Siddarth. He wanted to help.
Siddarth decided to build an affordable arm for his new acquaintance. He applied the creative skills he’d developed from earlier projects, including an award-winning STEM kit. “My mom showed me how to code,” he says, crediting her for introducing him to engineering.
Using a home 3D printer, Siddarth invented a prosthetic arm costing just $150. Traditional prosthetics often cost tens of thousands of dollars. Siddarth’s prosthetic is affordable, uses sustainable materials, and has simple controls. He felt great satisfaction knowing his invention was helping someone in need. His invention won praise at the 2024 National STEM Festival and drew national attention, including accolades from President Biden and the U.S. House of Representatives.
Early Spark and Family Influence
Siddarth’s started learning technology when he was seven years old, playing with a simple electronics kit his mom, Srilatha, gave him. He remembers vividly, “I fell in love instantly, creating something out of nothing.” His parents provided resources, tools, and the freedom to explore. This supportive environment helped Siddarth gain confidence to ask big questions and find creative answers. Siddarth, born in India, like many immigrants values new ideas and approaches.
From Curiosity to Real-World Solutions
Once Siddarth developed his low-cost prosthetic, he realized just how powerfully new ideas and new inventions change lives. When he lost his grandfather because of an undetected heart condition, Siddarth set out to create Circadian AI, a smartphone app that detects potential heart problems.
He spent eight months developing software that processes heart-sound recordings within seven seconds. Collaborating with hospitals in Texas and India, Siddarth gathered thousands of patient recordings to train his AI. Working closely with cardiologists and technicians, he identified crucial murmurs and arrhythmias and integrated these insights into his model, pushing accuracy above 95%. He also created custom noise-cancellation algorithms to handle noisy clinical environments, ensuring clarity without sacrificing diagnostic signals. Siddarth aligned his app’s data-logging, authentication, and reporting features with FDA and international regulations, facilitating quicker adoption.
Circadian AI provides rapid results using only a smartphone microphone, achieving over 96% consistency with clinical ECG and echocardiogram tests. With its simple “Healthy” versus “Risk Detected” output and clear next-step instructions, the app is an accessible tool ideal for rural clinics and underserved regions, requiring no specialized hardware beyond a standard smartphone. Siddarth says simply, “We weren’t just building software. We were building second chances.”
Mentorship and Growth
To further develop his skills, Siddarth joined the Young Entrepreneurs Academy (YEA!) in Frisco, Texas, where mentorship and training helped him refine inventions into marketable products through creative, design-thinking methods. “The YEA! program unlocked my potential,” Siddarth noted. Organizations like Project Invent provide similar support nationwide, connecting students with mentors to create real solutions to everyday problems.
Siddarth’s experience illustrates how small beginnings, such as a simple electronics kit or a brief encounter, can lead to significant change. His story highlights qualities like curiosity, persistence, empathy, and resourcefulness. These traits are not fixed and permanent. We all can cultivate these capabilities with practice and encouragement.
Through each project, Siddarth’s family and mentors reinforced essential lessons. One mentor’s motto stuck with him: “Fail just stands for First Attempt In Learning.” Siddarth embraces failure as a steppingstone and views obstacles as opportunities. He remains grounded and is quick to acknowledge how his parents kept him humble and focused. Now in high school, Siddarth continues to expand his horizons by playing competitive chess and experimenting with AI and robotics.
Speaking to other young inventors, Siddarth says, “Innovation is the heartbeat of progress …The tools are already in your hands.” Here are some ideas and actions to consider.
