Discover the design
Implant design
Conceptual structure: Sensors, a miniature battery, a wireless module and flexible leads work together within the implant.

Sensors and signals
Biopotential. Capture the smallest signals. ECG, EEG, EMG, EOG and gastrointestinal electrical activity. Choose electrodes and recording sites for cardiac, neural, muscular and digestive-system measurements.
Pressure. Follow pressure over time. Arterial, venous, left-ventricular, intracranial, bladder, intraocular and uterine pressure. Select sensing configuration and range for the target site.
Temperature. Keep temperature in view. Temperature sensing records changes alongside other channels and experimental events. Parameter range: 10–50 °C, precision 0.05 °C, sampling 0.01–1 Hz.
Activity. Put movement in context. Acceleration provides context for movement, awake behavior and circadian research: ±8 g, precision 0.001 g, sampling 1–200 Hz. The illustrative activity trace uses arbitrary units.
Glucose. Observe metabolic changes. Use a glucose-sensing configuration for longitudinal in vivo metabolic observation. Confirm sensor choice, usable duration and experimental conditions.
Oxygen saturation. Add an oxygen dimension. Observe oxygen-saturation changes with the appropriate optical sensing configuration and relate them to other physiological recordings.
Sensor interfaces
Air receiver
Connect up to 8 implants with one receiver.
Reach up to 10 m in open space.
Add an external antenna for complex cage racks.
Transfer data at a total rate of up to 2 Mbps.
Receive external triggers through sDIO.
Bring recordings into acquisition and analysis.

In vivo wireless charging
Recharge wirelessly without removing the implant. Build charging into the experiment schedule to support repeated use. Follow device and environmental requirements. Standby time, recharge cycles and continuous recording duration are distinct specifications.
Stimulation outputs
Combine optical or electrical outputs with recording and events. Waveform composition follows in the acquisition section.
Optical configurations include 470, 525, 561 and 635 nm; customization is available. Confirm wavelength, power and implant options for the study.
Electrical current range is ±10 mA with error ≤2% in the parameter sheet. Available channels and pulse settings depend on the selected configuration.
02 · Acquisition software
Tick the Air card and press Enter, then connect the implants you need. Yellow is waiting to connect, green is connected and normal, red is a signal fault; start once the battery is above 20% and the signal reaches 4 bars.
Double-click an implant to set sampling, reasonable range, real-time filtering and smoothing, alert limits, and the optical or electrical waveform, Sweep and Timer. Activate each channel before it can record.
Use Preview to check whether the data is reasonable — nothing is saved while previewing. Waveform, Sweep duration and Timer can all be verified there first.
Click Start to record and Stop to end the session. Name the file and add tags before recording, and configure Marker, Output and Trigger as the experiment requires.
This replay illustration shows the traces changing as the time window moves back and forth. Page mode shows one window at a time, Scroll mode adds new data at the right. Switch the timeline between seconds, days or milliseconds, drag the handles to resize the window, double-click to return to live data, and read markers and outputs in the Event row.
Load data from the drive on the Data page and export it, then run R-peak, heart-rate, delineation, HRV, pressure, respiration, sleep-staging, time-frequency and statistical analysis in Inper analysis.
Acquisition settings
Inspect sampling, preprocessing, events and saved configuration by function.
Set sampling rates and valid ranges per signal: biopotential 100–2000 Hz, pressure 1–500 Hz, temperature and glucose 0.01–1 Hz, activity 1–200 Hz, SpO₂ 1 Hz.
Band-pass, band-stop, notch and smoothing in real time; samples beyond the alert range are marked in red. Save the processing conditions with the data.
External signals, manual events and TTL output share one timeline: DIO input, manual markers and 2–9999 ms TTL output on data conditions.
Save parameters, check Trigger separately and log software and firmware versions. Both update online; analysis modules can be added.
Select a step or play the walkthrough.
Waveform composition
Optical stimulation supports seven waveform types; electrical stimulation supports square and constant waveforms. A Sweep contains up to eight segments. The illustration uses normalized amplitude and equal segment durations; configure actual output, timing and repetitions in the acquisition software.
Trigger timing
Start or stop immediately with Start / Stop, under direct operator control.
Wait for the configured delay after Start to coordinate preparation and timing.
Run at a scheduled time and use Repeat for recurring cycles. The instructions use a 24-hour clock.
Stop after the configured duration to bound a recording or stimulation run.
Trigger from an external device. When both Start and Stop use Exterior, select Realtime or Gate. Timer does not apply to optical/electrical stimulation triggered externally in these modes.
Conditional output
Follow the source signal, derived indicator, threshold condition and DIO output together.
03 · Analysis software

The analysis window shows multiple channels and markers. Review recorded channels on a shared timeline and relate them to experimental events.
Inspect changes around the same event.
Select a recording and time window, then enter the analysis for the signal of interest.
Check segments and annotations before interpreting derived indicators.
Signal-specific tools
Actual software screens show how recordings become annotations, trends and result tables.
Identify R peaks in the ECG and review beat locations against the original segment. Use P, QRS and T annotations to inspect morphology, amplitudes and intervals, relating detection points and results to the selected time window before subsequent heart-rate and rhythm analysis.
Start with the sequence of R–R intervals to inspect changes over time and heart-rate variability results. Review beat classifications and unusual points in the selected segment, then relate time-domain and frequency-domain results to changes in rhythm while retaining the analysis window and processing conditions.
Inspect each pressure cycle and relate applicable systolic, diastolic and mean-pressure indicators to the original segment, trends and result table. Review peak and trough detection in the context of the measurement site and time window, and compare changes around experimental events within the same recording.
Review EEG, EMG and sleep-stage annotations in the same recording. Time-frequency views and power spectra help relate signal features to different stages. EMG envelope, time-domain and frequency-domain results provide additional views for checking stage labels against the underlying signal.
Inspect respiratory cycles and frequency, and interpret inspiration, expiration and phase timing with the sensor orientation in mind. Review cycle boundaries against the original waveform, then relate results from the selected time window to experimental events and changes in respiratory rhythm.
