Abstract

A bio/chemical monitoring is important not only for medical but also health care management. For 20 years, we have developed several types of detachable sensors into human cavitas sites (conjunctiva, pharyngeal, oral cavity, etc.) with biocompatible materials and harmless MEMS techniques for daily medical & health care in the near future. In this contribution, ultra soft contact-lens biosensors for blood-sugar and -oxygen gas will be introduced as a non-invasive approach at the conjunctiva cavity. And we will demonstrate telemetric mouthguard sensors with BLE 4.0 (Bluetooth 4.0 low energy) unit as invisible & unconciouness sensing-devices in the oral cavity.
