Scientists have invented a mouthguard for teeth, which is a smart home control tool. Can be,

Smart mouthguard contains built-in pressure sensorsto detect certain patterns. These patterns are decrypted with 98% accuracy and can be used to control computers, smartphones and wheelchairs.
Bites cause mechanical deformation of contactsites and the consequences of this, which can be measured and processed using machine learning algorithms. The collected data is then used for high-precision remote control and operation of various electronic devices. The mouthguard itself weighs only seven grams. Its production currently costs SGD 100 and the team expects the cost to be substantially reduced with mass production.
