Abstract: A strain gauge sensor system is disclosed for monitoring changes in stain of a battery surface, said change in strain indicative of internal changes in the battery. The sensor system comprises a wire grid based sensor, the sensor electrically connected though for example a Wheatstone bridge to an RFID tag. In the presence of an RFID reader, the sensor system is activated, a signal representative of the resistance of the wire grid (and thus grid strain) transmitted to the reader, and the resistance value compared to resistance values for the healthy state of the battery.

Abstract: A laser direct write method used to transfer entire single components such as semiconductor bare dies or surface mount passive and active components on a substrate or inside recess in a substrate for making embedded microelectronics is disclosed. This method laser-machine the pockets, laser-transfer the individual components inside those pockets, and then laser-print the interconnects required to “wire” the components, thus resulting in a fully assembled embedded circuit required to make a fully functional microelectronic system.
