Thermoelectrics is a business impeded by the use of the toxic rare metal Tellurium. Commendably, there is a trend to alternatives in research but few volume sales as yet in any of the three uses. These are energy harvesting to make electricity where it is needed and the more successful cooling and heating, those last two constituting very-reliable, solid heat pumps.

The development of new technology often creates new opportunities to provide value to customers in new products. Electronic textiles have hundreds of potential use cases, many of which are being explored by different companies around the world. So where is the "killer app" for e-textiles?

IDTechEx have recently launched "Electrically Conductive Adhesives (ECAs) 2022-2032", a market research report detailing the technology of ECAs, a form of conductive joining technology. Electrically conductive adhesives (ECAs) are a growing competitor to lead-free solders and silver sintering technologies, and currently see use in several electronics applications, such as automotive electronics, consumer electronics, and display applications.
