A miniaturized ingestible temperature sensor for continuous internal monitoring (opens in new tab)

Ingestible electronic systems offer a minimally invasive means to continuously monitor core body temperature, providing critical insights into a range of health conditions. However, the size of ingestible sensors often limits their use, particularly in paediatric populations. Here we report a miniaturized ingestible temperature sensor for continuous internal monitoring. The device integrates a 1 mm × 1 mm low-power (10 nW) integrated circuit, a 5 mm × 5 mm antenna for wireless backscatter com...
