Wireless strain and displacement sensors wirelessly monitor structural health and integrity, and are made by printing inductor-interdigital capacitor sensing circuits on a variety of substrates, including ceramic substrates, with thermally processable conductive inks. Sensors of the invention can be employed to detect strain and displacement of civil structures, such as bridges and buildings. The sensors include sensing elements that are mounted or printed on stiff, inflexible substrates, which prevent the sensing elements from bending, stretching, or otherwise warping when the sensor is strained. An interlayer between the sensing elements allows the sensing elements to move with respect to each other during application of strain. Thus, strain causes the sensing elements to move but not to deform, causing changes in sensor resonance that can be detected through wireless radio-frequency interrogation. Because the sensing elements do not change shape when under strain, the sensor can undergo millions of measurement cycles before breaking.

Then, the first communication device transmits a preamble on the available radio channel after the time period. The first communication device thereafter transmits the data information on the available radio channel to the second communication device at a next fixed time instant following the transmission of the preamble.

The node schedules one or more of the wireless devices of the cellular network based on the first and second respective throughputs. Each of the wireless devices is scheduled for cellular communication together with the D2D communication of the assigned D2D pair when the first respective throughput exceeds the second respective throughput, or for only cellular communication when the first respective throughput is below the second respective throughput.

Angelita Wynn has driven a school bus for six years. Wynn was driving the kids back home on her afternoon run in Pittsburgh one day in March when she got word her job was going away. Over the radio. "Our dispatcher came across the radio saying that school was closed, so that's how I found out," Wynn said. "And that's the last time I've been in the bus." Her favorite thing about her job was the sense of freedom it offered, where driving can get you from one place to another. Her least favorite thing: It didn't pay a living wage. Wynn notes that most school bus drivers are retired or married to someone who brings in another income. "If you don't fit in those categories it can be a struggle," she said. She typically collects unemployment during the summer when school is not in session. But the abrupt layoff this spring and a weeks-long delay in getting her jobless benefits has thrown her for a loop. "My bank account is in the negative," Wynn said. "I've had to rely on savings that will
