ELECTRONIC SKIN AND MANUFACTURING METHOD THEREFOR
An electronic skin is manufactured by disposing an oxide thin film transistor (TFT), a pressure sensor, and a temperature sensor on a flexible substrate. The pressure sensor and the temperature sensor are respectively located on two sides of the flexible substrate. The oxide TFT includes a first TFT and a second TFT. The pressure sensor is configured to drive the first TFT, and the temperature sensor is configured to drive the second TFT. The method for preparing the electronic skin is to form an oxide TFT, a pressure sensor, and a temperature sensor by means of etching and deposition on a flexible substrate whose double sides are covered with conductive materials. The electronic skin provided in the present invention may simultaneously measure pressure and temperatures, and has a simple structure, a low working voltage, small power consumption, high sensitivity, and small interference between sensor signals.

Electrocardiography And Syncope Monitor Recorder
Physiological monitoring can be provided through a syncope sensor imbedded into an electrocardiography monitor, which correlates syncope events and electrocardiographic data. Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended-wear electrode patch and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The wearable monitor sits centrally on the patient's chest at the sternal midline and includes a unique narrow “hourglass”-like shape, significantly improving the ability of the monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and QRS interval signals, which indicate ventricular activity in electrocardiographic waveforms. The electrocardiographic electrodes on the electrode patch are tailored for axial positioning along the midline of the sternum to capture action potential propagation in an orientation that corresponds to the aVF lead in a conventional 12-lead electrocardiogram, which senses positive P-waves.
