Use of high frequency waves, such a millimeter waves, in many circumstances is prevented due to their inability to diffract around common obstacles. Disclosed herein is a system and method for transforming an incident high frequency wave. The system includes meta-atom pairs that define a surface. The meta-atom pairs generate an electro-magnetic response by interacting with an incident wave. This electro-magnetic response can be modulated by applying voltage to the meta-atom pairs. The electro-magnetic response transforms the incident wave into an emitted wave based on its controlled properties. The system and method are able to, by changing the voltage applied, steer the emitted wave a full 360 degrees as wells as transmit it through the surface without significant power loss. Embodiments enable the transmission through or around many obstacles that would normally interfere with high frequency waves.

A garment system comprises a garment substrate formed from one or more textile-based sheets, a distributed array of a plurality of resistive pressure sensors coupled to the garment substrate at a set of first specified locations. Each of the plurality of resistive sensors comprises a pair of first textile-based outer layers each having an electrical resistance of no more than 100 ohms and a textile-based inner layer sandwiched between the pair of first textile-based outer layers having an electrical resistance of at least 1 mega-ohm. The system also includes electronics configured to process signals from the distributed array of resistive pressure sensors to determine one or more physiological properties of a wearer of the garment substrate.

Systems and techniques for a low power wrist-worn RFID reader capable of reading RFID tags within the area of a localized personal body network. The wrist-worn reader provides a means for tracking how a user interacts with their environment. The wrist-worn reader may distinguish between tagged objects within the range of the reader and objects held by the user. The reader may also distinguish when a tagged object has been picked up and when it has been released.

Embodiments that relate to energy efficient gesture input on a surface are disclosed. One disclosed embodiment provides a hand-worn device that may include a microphone configured to capture an audio input and generate an audio signal, an accelerometer configured to capture a motion input and generate an accelerometer signal, and a controller comprising a processor and memory. The controller may be configured to detect a wake-up motion input based on the accelerometer signal. The controller may wake from a low-power sleep mode in which the accelerometer is turned on and the microphone is turned off and enter a user interaction interpretation mode in which the microphone is turned on. Then, the controller may contemporaneously receive the audio signal and the accelerometer signal and decode strokes. Finally, the controller may detect a period of inactivity based on the audio signal and return to the low-power sleep mode.
