TV Remote Control

Most appliances in modern households are remote-controlled, from televisions to stereos and even lighting. Some devices like air conditioners have their remote controls in idle mode for the majority of the time. In a typical use case, they only have a few button presses per day. On the other hand, stereo, set top box and television remotes are used more frequently with an average consumer pressing the buttons hundreds of times per week. These remotes tend to have a very limited battery lifetime and require periodic replacements.

Billions of primary batteries are discarded by us every year polluting huge swathes of land and nearby water bodies. A portion of this pollution can be attributed to the primary AA or AAA cells powering most TV and set top box remote controls globally. TV remotes generally last a few months before requiring battery replacement thereby adding a significant amount of toxic waste being released in the environment. Recently, many TV manufacturers have started to embrace energy harvesting solutions to extend the remote controls’ battery lifetime and decrease the negative impact of e-waste on the environment. However, the additional cost of energy harvesting poses a significant challenge to the widespread adoption of the technology, especially for this cost-sensitive application.

Nowi presents a revolutionary power management solution which aims to overcome the cost barrier to energy harvesting with its lowest BOM cost, extremely small footprint, and simplicity in integration. For more information, please refer to the Nowi TV Remote control application note.
