Multi-modal sensing wearable device for physiological context measurement

A method, comprising:

• disposing, in an apparatus, a first sensor having at least a first electrode to provide a first contact with a user's body in response to mounting of the apparatus on the user's body, and a first sensing layer disposed on the first electrode;
• disposing, in the apparatus, a second sensor having at least a second electrode to provide a second contact with the user's body in response to mounting of the apparatus on the user's body, and a second sensing layer disposed on the second electrode;
• and
• electrically coupling the first and second electrodes of the first and second sensors with a processing block of the apparatus, to facilitate provision of first and second signals generated by the first and second layers in response to vibration, and to provide to the processing block a voltage signal generated by the user's body, to perform measurements of a user's physiological context, wherein the voltage signal comprises a difference between respective voltages on the first and second electrodes of the first and second sensors.

An apparatus, comprising:

• a processing block;
• and
• first and second piezoelectric sensors coupled with the processing block, wherein the first and second sensors include respectively first and second electrodes to provide contact with a user's body in response to mounting of the apparatus on the user's body,
• wherein the processing block is to perform measurements of a user's physiological context during the contact of the user's body with the first and second electrodes, based at least in part on a voltage signal generated by the user's body and provided to the processing block via the first and second electrodes.
