摘要：

Biologic systems frequently have electric activity associated with them. This activity can be a constant de electric field, a constant flux of charge-carrying particles or current, or a time-varying electric field or current associated with some time-dependent biologic or biochemical phenomenon. The mechanism of electric conductivity in the body involves ions as charge carriers. Thus, picking up bioelectric signals involves interacting with these ionic charge carriers and transducing ionic currents into electric currents required by wires and electronic instrumentation. Calcium ion is so important in our body, which plays a crucial role in metabolism.The common methods of detecting calcium ion include radioactive tracer method, activation shine protein method, etc, we choose calcium ion sensing needle as a tool to detect the calcium ion in the acupoint.
