Abstract Multi-sensor monitoring devices that use skin surface or
implanted sensors are susceptible to changes in temperature, sweat,
and movement, such that the measured data cannot be used. This
paper presents an automatic approach to detect such erroneous
sensors. It is based on the assumption that valid measurements are
related by a reconstruction model, while measurements from
erroneous sensors are unrelated. The method estimates the data at
each sensor based on the measurements from all other sensors, and
