Ultra-low-power sensors carrying genetically engineered bacteria can detect gastric bleeding or other gastrointestinal problems. This “bacteria-on-a-chip” approach combines sensors made from living cells with ultra-low-power electronics that convert the bacterial response into a wireless signal that can be read by a smartphone...
