HSI Sensing developed the world’s smallest reed switch which is now used in ingestible pills that provide remote medical data during space explorations.
The customer currently dispenses ingestible pills in order to track and record medical data remotely. These pills are primarily used for astronauts to measure their core body temperature; the pills also act as a gastrointestinal camera. The customer was seeking a reed switch solution to replace standard hall sensors because the switch provides isolation and pulls zero power in the ‘off’ state.
HSI Sensing developed the world’s smallest reed switch, the HSA-12077 Form B Reed Switch, to be used in these ingestible pills. HSI paired the switch with a magnet that is embedded into the packaging of the pill to preserve the battery. The pill turns on when it is removed from the package and requires no power.
