Thread-based real-time monitoring of bodily fluids

A wearable sensor for monitoring an external bodily fluid includes a sensor thread, a wick, a substrate, and a communication interface all of which are disposed on a substrate. The wick wicks the external bodily fluid to a functionalized region of the thread. The communication interface transmits, to an external device, data indicative of what the sensor thread has measured in said external bodily fluid. The external device can then carry out real-time analysis or storage.

Identifying substrate waste sites

In one example in accordance with the present disclosure, a system is described. The system includes a fluidic die to advance across an ejection path relative to a substrate. The fluidic die includes a channel to contain a portion of a sample fluid, a sensor to detect passage of a particle within the sample fluid into the channel, and an ejection device. The ejection device is to eject the particle. The system also includes a controller. The controller identifies discrete locations along the ejection path as waste sites as the fluidic die advances along the ejection path. This is done by 1) classifying the particle as a target particle or a non-target particle, 2) upon identification of a target particle, ejecting the target particle to a target site of the substrate, and 3) upon identification of a non-target particle, ejecting the non-target particle to a waste site.
