What is Smart India Hackathon (SIH) 2026?

Smart India Hackathon (SIH) is the world’s biggest open innovation hackathon organized by the Ministry of Education, AICTE, and MIC, where student teams build hardware and software solutions for problem statements submitted by Government Ministries, Departments, and State Agencies.

How many problem statements are released in SIH 2026?

SIH 2026 features 226 official problem statements, comprising 172 Software category statements and 54 Hardware category statements across themes like Smart Automation, Agriculture, Disaster Management, MedTech, Clean Water, and Cybersecurity.

How does the SIH ONE AI Team Matchmaker work?

The SIH ONE Matchmaker takes your 6-member team’s frontend/backend/AI skills, hardware experience, domain preferences, and exclusions, then runs a multi-factor weighted scoring algorithm to rank the top 25 highest-fit problem statements.

How does the smart insole detect that a runner is overpronating during their stride?

The embedded 9-DOF IMU measures the angular velocity of the subtalar joint at initial contact, while the force matrix measures the medial vs lateral displacement of the Center of Pressure (CoP); an inward roll angle exceeding 15° triggers an overpronation alert.

How does real-time haptic biofeedback help prevent athletic stress fractures?

When the peak ground reaction force (measured by the heel piezoresistive sensor) crosses 2.8 times the runner's calibrated body weight, a micro-vibration motor inside the insole buzzes instantly, cueing the runner to soften their footfall and increase cadence.

How does the hardware survive the mechanical abuse and sweat of long-distance running?

The electronic module is hermetically sealed in a water-resistant (IP67) silicone casing with conformal coating on electronics, while the flexible sensor layer is laminated between moisture-wicking, anti-bacterial EVA foam insoles.

30-Second Plain English Summary

AICTE Open Innovation: Fitness & Sports (Hardware) — Runners, field athletes, and orthopedic patients in India suffer from chronic stress fractures, ligament tears, and gait asymmetries because standard fitness trackers only count daily wrist steps without measuring ground reaction impact force or foot pronation. Build a Smart Instrumented Athletic Insole and Gait Biomechanics Wearable featuring a flexible matrix of thin-film piezoelectric force sensors, a 9-DOF IMU, Bluetooth Low Energy (BLE) micro-controller, and real-time athletic gait analytics.
