1. A measurement system comprising:
a vibration generation unit that generates sound or vibration in response to a change in an environmental state quantity;
a vibration-driven energy harvesting unit that generates electric power using the sound or vibration generated by the vibration generation unit, wherein the vibration generation unit includes a structure configured to impact the vibration-driven energy harvesting unit to generate the sound or vibration,
wherein the vibration generation unit includes a deformation member whose shape suddenly changes from a first shape to a second shape in response to the change in the environmental state quantity,
wherein the environmental state quantity is pressure and the deformation member is a pressure bulkhead whose shape suddenly changes in response to a change in pressure; and
a transmission unit that is driven with the electric power generated by the vibration-driven energy harvesting unit and transmits a transmission that includes predetermined information.
