The present invention provides an apparatus for applying electrical stimulation to cells in a liquid culture medium without using electrodes immersed in the liquid culture medium. This apparatus is an electrical stimulation apparatus A for electrically stimulating cells in a liquid culture medium (). A liquid culture medium vessel () includes: a ring-shaped recess () for holding the liquid culture medium (); and a through hole () formed within the ring-shaped recess (). A magnetic core () is made of a magnetic material and disposed such that a portion thereof is inserted through the through hole () of the liquid culture medium vessel (). An excitation coil () is wound around the magnetic core (). A coil power supply () supplies a varying current to the excitation coil ().

Apparatus and method for non-contact electrical stimulation of cells in liquid culture medium

A smaller-sized, more lightweight, and power-saving successive magnetic pulse device is provided. A discharging circuit section K is configured by connecting, in series in a loop, a magnetic therapy pulse coilconfigured to generate an eddy current in a target part, a charging/discharging capacitor, and a switching semiconductor elementconfigured to supply a discharge current from the charging/discharging capacitorto the pulse coil. A step-up transformerincludes a primary-side coilconnected to an AC power supplyand a secondary-side coilconnected to input terminalsof a full-wave rectifying circuit. A control unitis connected to a switching semiconductor elementand controls conduction timing of the switching semiconductor element. The full-wave rectifying circuithas output terminalsconnected to both terminals Pand Pof the charging/discharging capacitor, respectively. An inductoris connected between the output terminalof the full-wave rectifying circuitand the terminal Pof the charging/discharging capacitor
