BioMedical Life Systems Micro Plus® Microcurrent Stimulator | KMICP

The BioMedical Life Systems Micro Plus® is a portable, prescription microcurrent electrical nerve stimulator (MENS) with dual outputs, adjustable microamp and milliamp ranges, selectable polarity, and clinician-adjustable pulse characteristics.

Micro Plus differs substantially from a conventional TENS or NMES unit. Its dedicated microcurrent range extends from 0 to 1000 microamps (µA)—currents small enough that stimulation may be below or near sensory perception depending on the prescribed settings and individual user.

For protocols that require a higher output range, the device can also be switched to 1–5 mA, giving the prescribing practitioner considerably more flexibility than a microamp-only device.

The Micro Plus is FDA-listed as a prescription-use Class II transcutaneous electrical nerve stimulator for pain relief and should be operated according to the prescribing practitioner's instructions.

Micro Plus at a Glance

Microcurrent Instead of Conventional Milliamp TENS

The simplest way to understand Micro Plus is to compare microamps and milliamps.

One milliamp equals 1,000 microamps. Conventional TENS devices generally operate in milliamp-level current ranges designed to create a clearly perceptible sensory response. Micro Plus adds a dedicated microamp range of up to 1,000 µA.

That distinction matters because a correctly operating Micro Plus may produce little or no obvious tingling while operating in its microcurrent range. Lack of a strong sensation does not automatically mean that the unit has no output.

For a broader discussion of sensory-level electrical stimulation, see our TENS vs. NMES guide.

Dual Microamp and Milliamp Output Ranges

Micro Plus gives the prescribing clinician two available amplitude ranges:

This gives the device a wider operating envelope than microcurrent units restricted exclusively to sub-milliamp output.

Because the two scales represent different units of current, users should confirm that the correct range is selected before increasing amplitude.

Three Selectable Polarity Settings

The Micro Plus provides:

• Positive polarity
• Negative polarity
• Bipolar operation

Polarity is therefore a deliberate treatment parameter rather than a fixed characteristic of the device.

The appropriate polarity, output range, electrode arrangement, and stimulation parameters depend on the prescribed protocol. Follow the Micro Plus operating instructions and the directions of the treating practitioner rather than substituting settings from another electrotherapy device.

Adjustable Frequency and Pulse-Train Duration

Micro Plus provides more manual parameter control than many preset-oriented portable stimulators.

These specifications are useful when a clinician wants a reproducible protocol rather than a collection of generic numbered programs.

Micro Plus vs. TENS vs. NMES

Microcurrent, TENS, and NMES all deliver electrical stimulation through electrodes placed on the skin, but the electrical characteristics and treatment objectives differ.

If the objective is deliberate muscle contraction rather than microcurrent stimulation, compare the Balego EMS Digital NMES Stimulator.

If the treatment plan calls for conventional TENS, NMES, interferential, and Russian stimulation in one rechargeable unit, compare the InTENSity Select Combo II.

These devices should not be treated as interchangeable solely because all of them connect to surface electrodes.

What Comes With the Micro Plus?

Each Micro Plus kit includes:

• 1 Micro Plus® device
• 4 reusable 2" × 2" electrodes
• 2 BMLS touchproof lead wires
• 1 9V alkaline battery
• 1 zippered carrying pouch
• Belt clip
• Instruction manual

The unit therefore arrives as a complete stimulation kit rather than a bare stimulator requiring the basic accessories to be purchased separately.

Compact, Battery-Powered Design

The Micro Plus measures approximately 3.9 × 2.75 × 1 inch and weighs about 4.6 ounces.

A standard 9V battery powers the unit, allowing it to remain portable for clinic, professional, and prescribed home-program use without requiring charging between sessions.

Replacement Electrodes

Micro Plus is supplied with four reusable 2-inch square electrodes.

Electrode condition remains important even at low-current settings. Poor adhesion, dried hydrogel, damaged pads, or inadequate skin contact can change current distribution and make stimulation inconsistent.

For replacement options, see our reusable TENS/NMES/FES electrodes. Confirm connector compatibility and follow the Micro Plus instructions when replacing the original BMLS electrodes or leads.

Is Microcurrent Supposed to Be Felt?

Not necessarily.

BioMedical Life Systems specifically distinguishes Micro Plus microcurrent from conventional milliamp-level TENS because the lower current can be below normal sensory perception.

A user should therefore not continuously increase intensity simply because no strong tingling is present. The output range and treatment parameters should follow the prescribed protocol.

If the treatment objective requires a strong sensory TENS sensation instead, Micro Plus may not be the appropriate modality or operating range.

FDA and Prescription Status

Micro Plus is listed by the FDA under product code GZJ—Stimulator, Nerve, Transcutaneous, For Pain Relief.

Use the device only according to its labeling and the prescribing practitioner's instructions.

Technical Specifications

Frequently Asked Questions

What is the Micro Plus?

Micro Plus is a portable dual-channel microcurrent electrical nerve stimulator manufactured by BioMedical Life Systems. It provides both a 0–1000 µA microamp range and a 1–5 mA low-milliamp range.

What does MENS mean?

MENS is commonly used to mean microcurrent electrical nerve stimulation. It refers to electrical stimulation delivered at substantially lower current levels than those commonly used by conventional TENS.

Is Micro Plus the same as a TENS unit?

Not exactly.

FDA classifies Micro Plus within the transcutaneous nerve-stimulator category for pain relief, but its electrical design includes a dedicated microcurrent output range and selectable polarity that distinguish it from conventional milliamp-level TENS devices.

For a conventional multimodality electrotherapy option, compare the InTENSity Select Combo II.

What is the maximum microcurrent output?

The dedicated microamp range is adjustable from 0 to 1000 µA.

Can Micro Plus also deliver milliamps?

Yes. Its separate milliamp setting is adjustable from 1 to 5 mA.

What polarity settings are available?

Positive, Negative, and Bipolar.

What is the frequency range?

The detailed BMLS device specification lists an adjustable pulse rate from 0.05 to 120 Hz.

What is the carrier frequency?

14,000 Hz.

Does microcurrent always produce a tingling sensation?

No. At microamp-level output, stimulation may be minimally perceptible or not consciously felt.

How many channels does Micro Plus have?

Two.

How many electrodes are included?

Four reusable 2" × 2" electrodes are included.

What battery does it use?

One standard 9V alkaline battery is supplied with the kit.

What is the manufacturer's part number?

KMICP.

What is the GTIN?

The FDA-listed Primary UDI-DI / GTIN-14 is 00857771003163. The corresponding UPC-A is 857771003163.

Is Micro Plus an over-the-counter device?

No. The FDA's GUDID record identifies Micro Plus as prescription use = Yes and OTC = No.

What is the HCPCS code?

BioMedical Life Systems currently lists E0730.

What warranty does it have?

The current manufacturer product page specifies a 2-year limited warranty.
