Hypothermia is a common problem for malnourished children. In low and middle income countries there is frequently not enough nursing staff to take regular temperature measurements of the children and hypothermia does not have any obvious visible signs until it is too late to treat. The wireless temperature sensor we developed takes an axillary temperature using a thermistor connected to a band around the arm and uses Bluetooth to connect to an Android tablet. The nurses can continuously monitor the patients from wherever they are in the hospital. An alarm can notify the nurse when the temperature drops too low. They system can support 50-100 sensors with one tablet. The sensors are fully cleanable and reusable with no disposable parts to keep the costs low. The system has been demonstrated in Malawi and work is being done now to ready for clinical evaluation.
