Abstract: A biosensor capsule having a generally cylindrical housing with a plurality of sensors including a radiation sensor including a radiation emitter and a radiation detector and at least one additional sensor. A processor uses data feeds from the radiation sensor and also from one more additional sensor of a different type. Additional sensors may be pressure or pH sensors to provide sensor signals to detect location along the GI tract in use. There may be a camera, and data derived from other sensors may be embedded in a video feed timeline. The capsule may have an asymmetric weight distribution to help keep sensing parts immersed in liquid.

Abstract: A biosensor system has a capsule with a housing configured for ingesting in a mammal GI tract, being cylindrical with domed ends. The housing forms an external space akin to a “cut-out” shape with two opposing transparent walls facing each other in the longitudinal direction and a base wall facing radially. An LED emitter emits at a number of wavelengths in time sequence, and radiation is detected by a photo-detector via the wall which forms a concave lens. An antenna is for wireless transmission of data to an external device and is in the form of conical spiral in an overall conical shape, located for optimum space efficiency in a domed end. A battery compartment is at the opposed end of the housing, separated from the antenna by the external space.
