To prevent indirect cross-contamination, people have devised various strategies: wearing gloves, using alcohol-based hand sanitisers, and using paper tissues, amongst other measures, to minimise the potential risk of infection caused by direct contact (see image below).

Whilst people are extremely cautious about lift buttons, they often overlook the entry and exit buttons on access control systems (see image below).

However, in everyday home life, there are many easily overlooked details that may lead to indirect transmission of viruses, and the key word for these transmission routes is ‘touch’.

As people place greater emphasis on and pursue a healthy lifestyle, it is anticipated that home appliances with automatic sensor functions will experience a surge in popularity.

The video demonstrates Sil傑’s 24GHz millimetre-wave short-range radar, which can be used for contactless switching applications. This prevents indirect transmission caused by direct hand contact with switches and similar surfaces.

The pandemic will eventually subside, and Sijie’s millimetre-wave radar will further contribute to the smart home IoT sector, bringing people a harmonious and healthy lifestyle.

Stay strong, Wuhan; stay strong, China.
