RE: Battery free15 May 2021 11:36
The 30min webinar indicated sectors that are large, growing with serious battery issues.
Increasing major growth sectors for electronic devices are now LPWAN (Automation, security, safety, productivity etc - ubiquitous sensors. Will be deployed in billions if fit-and-forget, affordable versions arrive) and SRWC (short wave wireless comms - Bluetooth, Zigbee etc - signals travel from a few cms to several metres, eg. infared, RF. Total many billions but that includes some of the others (? - LPWAN i presume) and many AC mains powered devices. EAS (electronic article surveillance) sector has had so far the largest battery need but internet shopping has made the retail shop security and garment tagging use of batteries decline.
Elsewhere came across Aowei, Chinese manufacturer, now In EU providing Skeleton type products for buses, renewables. Korchip (Korea) have just 2 products in a prismatic TR series.
