The use of PTC resistors maintains the simplicity of the implementation while reducing the associated power losses during normal operation. Power supplies which qualify as LPS are recognized as unlikely to cause electrocution or a fire due to the limitations on the output current and voltage they can deliver to a load. Regulating Network Providing Power Limiting This method is common in modern power supplies due to the low cost and wide availability of the required integrated circuits. The current limiting device must be either a fuse or a non-adjustable, non-auto resetting, and electromechanical device i. Devices Limiting Current Delivered to the Load Power supplies with external current limiting devices can be classified as LPS even if they do not contain one of the three means of limiting power delivery listed above. Conventional batteries were not designed with these criteria in mind. The electric organ of the knifefish Electrophorus electricus commonly known as the electric eel is, however, an example of an electrical power source that operates within biological constraints while featuring power characteristics that include peak potential differences of volts and currents of 1 ampere 1 , 2. Additional Resources. Linear or Non-Linear Impedance Providing Power Limiting An impedance in the form of a conventional resistor or PTC resistor can be placed in series with the power conductors to limit the power delivery capability of the power supply. The system uses a scalable stacking or folding geometry that generates volts at open circuit or 27 milliwatts per square metre per gel cell upon simultaneous, self-registered mechanical contact activation of thousands of gel compartments in series while circumventing power dissipation before contact. While being simple to implement, conventional resistors are seldom employed for this purpose due to the power dissipation of the resistors causing a reduction of the conversion efficiency of the power supply. Inherent Power Limiting This class of circuits does not require additional design considerations to ensure the limited power delivery capability as internal components are incapable of delivering power in excess of the limits. Understanding the basic specifications for LPS power supplies will help to explain why certain power supplies qualify as LPS while others do not. The benefit to customers of LPS power supplies is system installers can follow relaxed requirements regarding the wiring and physical installations of loads powered by modules certified as LPS.

Unlike typical batteries, these systems are soft, flexible, transparent, and potentially biocompatible. The electric organ of the knifefish Electrophorus electricus commonly known as the electric eel is, however, an example of an electrical power source that operates within biological constraints while featuring power characteristics that include peak potential differences of volts and currents of 1 ampere 12.

The classic example of a component limiting power delivery capacity is the winding resistance of an isolation transformer. Additional Resources.

A power supply can be certified as conforming to LPS if it employs an over current protection device i. Regulating Network Providing Power Limiting This method is common in modern power supplies due to the low cost and wide availability of the required integrated circuits. Here we introduce an electric-eel-inspired power concept that uses gradients of ions between miniature polyacrylamide hydrogel compartments bounded by a repeating sequence of cation- and anion-selective hydrogel membranes. These characteristics suggest that artificial electric organs could be used to power next-generation implant materials such as pacemakers, implantable sensors, or prosthetic devices in hybrids of living and non-living systems 3 , 4 , 5 , 6.
