Make a call with your finger? It must be digit-al technology

IT MIGHT look a little undignified but now you can ‘hear’ your mobile telephone calls by simply shoving a finger into your ear thanks to the £200 SgNL (pronounced ‘Signal’) wristband.

‘It works by sending vibrations through the skin,’ says inventor min Jae Kim, who claims that the gadget prevents the risk of your call being overheard by eavesdroppers.

Improvements have been made on earlier trial models in order to better the sound, make it sharper and block out outside noises.

A microphone inside the wristband enables you to talk on the phone. the battery is usable from one charge for a maximum of four days, providing almost four hours of active use. SgNL will be available in the UK this summer.
