Shape-memory alloy: Difference between revisions

The first high-volume product (> 5Mio actuators / year) is an automotive valve used to control low pressure [[pneumatic]] bladders in a [[car seat]] that adjust the contour of the lumbar support / bolsters. The overall benefits of SMA over traditionally-used solenoids in this application (lower noise/EMC/weight/form factor/power consumption) were the crucial factor in the decision to replace the old standard technology with SMA. The great potential of SMAs to expand in various automotive functions and conditions are due to their attractive attributes and flexibility, which may pass all the stringent requirements in automotive applications, especially for applications with lower bandwidth requirement and moderate temperature operation; and ideally suited with the ‘drive-by-wire’ technology<ref>{{cite journal|author=Jaronie.MJ, M.Leary, A.Subic |title=Shape memory alloys in automotive applications|journal=Applied Mechanics and Materials |year=2014|volume=663|page=248-253|url=http://www.scientific.net/AMM.663.248}}</ref>.
