Abstract: A smart telehealth ECG recording system includes a wearable patch to be worn on a user's skin. The wearable patch includes a stretchable substrate, a pair of electrodes mounted in the stretchable substrate and configured to measurement a voltage signal across the user's skin to produce ECG data, a mechanical sensor configured to measure a pulse from the user's body to produce pulse data, an acceleration sensor configured to measure a movement of the user to produce movement data, an antenna over the stretchable substrate and in electric communications with the pair of electrodes, the mechanical sensor, and the acceleration sensor, wherein the antenna is configured to wirelessly transmit the ECG data, the pulse data, and the movement data associated with the user, and a circuit electrically connected with the pair of electrodes, the mechanical sensor, the acceleration sensor, and the antenna.

Abstract: A wearable thermometer patch for monitoring healing of a wound on a user's skin includes a circuit substrate comprising an electric circuit, a first temperature probe unit comprising a first temperature sensor in electric connection with the electric circuit in the circuit substrate and a second temperature probe unit comprising a second temperature sensor in electric connection with the electric circuit in the circuit substrate. The first temperature probe unit and the second temperature probe unit are located respectively at a first position and a second position along a first direction. The wearable thermometer patch can be attached near a wound on a user's skin with the first direction is toward or away from the wound. The first and the second temperature probe units can measure temperature values at different distances from the wound on the user's skin. A temperature gradient is calculated based on the temperature values.

Abstract: One or more sensors sense patient heart rate and patient activity and provide related signals to a processor. The processor is responsive to sensor signals and obtains an activity threshold based on historical patient heart-rate signals and historical patient activity signals. The processor periodically derives a correlation value from current patient heart-rate signals and current patient activity signals and compares the correlation values to the activity threshold. A start of activity is noted when a correlation value exceeds the activity threshold; while an end of activity is noted when a correlation value fails to exceed the activity threshold. Activity is identified as exercise when correlation values continue to exceed the activity threshold for a predetermine amount of time, while an end of exercise is noted when correlation values fall below the activity threshold for a predetermined amount of time.
