Adhesive tape platform with form factor for improved sensing and external sensor probe
A wireless sensor device includes a flexible substrate, a cover layer on the flexible substrate, a device layer between the flexible substrate and the cover layer, and a printed circuit board connecting components of the device layer including an electrostatic discharge protected port for connecting an external sensor probe to the wireless sensor device. The device layer includes a processor, a memory, a battery, a first wireless communication system, and one or more onboard sensors; and a printed circuit board connecting components of the device layer comprising an electrostatic discharge protected port for connecting an external sensor probe to the wireless sensor device. The external probe allows for the wireless sensor device to perform sensor readings in environments that are too extreme or hostile to the wireless sensor device, while the wireless sensor device is safely isolated from the extreme or hostile environment.
