Physiological monitoring of a baby is carried out from a fabric patch (2) that is attached by fibre hook-and-eye fastening to the ba- by's conventional, stretchable vest (1). The laminated patch (2), which bridges the baby's thoracic and abdominal regions, includes a con- cealed substrate (4) that carries piezo-electric film strips (10, 11) which sense, in those regions respectively, elastic deflections of the vest (1) caused by the baby's respiratory and heart functions. Signals from the strips (10, 11), together with a body-temperature signal from a thermistor (17, Figure 4), are processed and transmitted via an in- ductive-loop antenna (19) of the patch (2), to a remote unit (21, Figure 5) for further, more detailed processing to derive representation inter alia of thoracic-abdominal synchrony/asynchrony. The result is stored and monitored against stored clinical-data for display and alarm operation; the stored data is accessed by a data logger (31, Fi- gure 5) for detailed analysis. Patch-attachment can be under a flap (43, Figure 6) bridging an opening (44) in the vest (41), or may be in- ternally, rather than externally, of the vest.
