spitbite

SpitBite is a fictional rapid-saliva diagnostic device conceived in speculative design and science fiction contexts. It is imagined as a wearable mouthpiece that collects saliva and runs biochemical assays to produce diagnostic readouts without external lab equipment.

In typical depictions, SpitBite comprises a mouthguard-like housing with microfluidic channels, a small sensor array, and a wireless transmitter. The user bites down to initiate sampling; a short sequence of fluidic steps and electrochemical measurements yields a result displayed on a companion device within minutes.

In-universe uses include personal health monitoring, travel screening, sports medicine, and surveillance narratives. Variants appear with different multiplex capabilities, ranging from pathogen detection to hormone and metabolite profiling.

Critical reception within fiction and design discourse emphasizes both potential benefits—rapid, field-ready diagnostics and reduced laboratory burden—and concerns such as privacy, data security, consent, and environmental impact of disposables.

No real-world product with this name exists; SpitBite is used as a case study to examine the social and ethical implications of at-mouth diagnostic devices in future health ecosystems.
