Integrated and flexible battery securing apparatus

A wireless sensor comprises:

• an environmental sensor;
• a radio frequency (RF) front end;
• a power harvesting circuit;
• a battery;
• an input/output module;
• a processing module operably coupled to the environmental sensor, the RF front end, the power harvesting circuit, the battery and the input/output module;
• a first printed circuit board (PCB) section that includes:
• a mounting section for the processing module;
• a first battery connection for providing an electrical connection to a first terminal of the battery;
• and
• a first mechanical coupling apparatus;
• a second PCB section that includes:
• a second battery connection for providing an electrical connection to a second terminal of the battery;
• and
• a second mechanical coupling apparatus;
• and
• a flexible section coupled to the first PCB and the second PCB, wherein, when the flexible section is in a first flex position, the first and second PCBs are at a distance where at least one of the first battery connection and the second battery connection is not electrically coupled to the respective one of the first and second terminals of the battery, and wherein, when the flexible section is in a second flex position, the first mechanical coupling apparatus is mechanically coupled to the second mechanical coupling apparatus, the battery is electrically coupled to the first and second battery terminals and is mechanically held in place between the first and second PCB sections.
