ScienceBioresorbable battery reportedly worked for up to three days in pig stomachs
A science roundup describes a paper-like battery that powered ingestible RFID and stomach-stimulation systems, while noting that not all the electronics can break down after use.
TLDR
A user's science roundup says researchers built a paper-like magnesium–molybdenum trioxide battery with a peak voltage of 1.84 volts. It reportedly powered ingestible radio-frequency identification (RFID) and gastric-stimulation systems and remained functional in pig stomachs for up to three days. The post says the battery can disappear after use, but the full electronic system is not yet universally bioresorbable. It identifies human safety and fully bioresorbable electronics as next steps.
