    Tiny transient sensors, smaller than a grain of rice, which can measure pressure, temperature, pH, motion, flow, and potentially specific biomolecules, stand to permanently improve patient care, have been developed by researchers at at the University of Illinois at Urbana-Champaign.
    These sensors can wirelessly relay critical health information and then gently melt away.
    They generally contain biodegradable silicon-based piezoresistive sensors, which change their electrical resistance with slight bending, surrounded by more silicon, magnesium, and a dissolvable copolymer, poly(lactic-co-glycolic acid) (PLGA), which is already used in medical devices.
    Which means that the sensors are made of elements and minerals that we already eat and drink.
