AMI Semiconductor, Pocatello, Idaho, has been selected by Interton, Plymouth, Minn, to develop advanced wireless capabilities in hearing devices through an ultra-low power radio frequency (RF) subsystem.
Adding wireless technology to modern hearing devices is a challenge given the battery life expectations of users. This escalates the requirement for the signal processing and wireless communication hardware within the hearing aid to be tightly integrated so that it can operate with extremely low power consumption and high fidelity.
“AIM Semiconductor has clearly demonstrated expertise in ultra-low power wireless technology for implanted medical devices, and we are quite familiar with their advanced digital signal processing technology for hearing aid,” says Christian Gormsen, managing director of Interton. “Based on their diverse expertise and proven track record, selecting AMI Semiconductor’s RF solution with the critically important low-power attribute was a logical choice.”
“Our relationship with Interton is a further demonstration of our total customer solution expertise for the evolving needs of the hearing aid market,” says Todd Schneider, vice president of AMI Semiconductor’s medical and wireless business unit. “Interton has always been at the forefront of launching innovative products, and we look forward to helping Interton integrate even greater functionality into their hearing aid devices without compromising on battery life.”
The RF and signal processing subsystems will be packaged in a hybrid assembly supplied by medical microelectronics supplier, IntriCon Corp (Resistance Technology Inc), Arden Hills, Minn. IntriCon will also offer a version of the RF technology to hearing aid manufacturers who require “ready-to-go” solutions.
