Hemesh Chadalavada: Alpha Monitor
Alpha Monitor — wristband alerting caregivers when a dementia patient wanders.
In 2019 Hemesh's grandmother, who has Alzheimer's, left a gas stove on and wandered at night. His wristband uses a gyroscope-based algorithm to tell sleeping from standing from walking, reads pulse and temperature, detects falls and alerts a caregiver's base unit; later versions use long-range LoRa radio so it works without Wi-Fi. He built about twenty prototypes, won the Pradhan Mantri Rashtriya Bal Puraskar in 2021 (not 2023, as some profiles say) and Samsung Solve for Tomorrow in 2022, and is now at Rice University.
