Embodiments of the present disclosure provide for an apparatus for opportunistic measurements and processing of a user's context. In one instance, the apparatus may include a processing block, a first sensor having first and second electrodes disposed on a work surface of the apparatus, to provide first readings of a user's physiological context in response to a contact between the electrodes and respective hands of a user, and a second sensor coupled with the processing block and having a sensitive surface embedded in one of the first or second electrode. The second sensor may provide second readings of the user's physiological context and a wake-up signal to the processing block in response to proximity of one of the hands to the sensitive surface. The processing block may facilitate process the user's physiological context in response to a receipt of the wake-up signal. Other embodiments may be described and/or claimed.

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.
