Medication Management System Using Dual-Band In-/Out-body Wireless Communication

Recently, the body area network (BAN) has been studied and widely developed.The system generally uses the 400 MHz and 2.4 GHz bands.Therefore, the antenna of the in-body sensor is large, and the miniaturization of an in-body sensor is difficult.When a high-frequency band such as a millimeter wave can be adopted, the sizes of the antenna and in-body sensor can be reduced by using an on-chip antenna.In this paper, a millimeter-size wireless device for the administration of medication is described, including the antenna for in-/out-body communication, wireless power transfer for small sensor chips, and wireless communication device.
